Iris har hjulpet Team Flash i Central City i seks måneder, men nægter at sørge over Barry. En flyvende samurai med superkræfter dukker op i Central City og truer med at ødelægge byen, hvis den rigtige Flash ikke møder ham. Cisco afslører, at han har formuleret en måde at bringe Barry tilbage på uden at destabilisere Speed Force og opsøger Caitlin for at få hjælp, men får forbud af Iris mod at bringe Barry tilbage. Mod Iris' ordre lykkes det Team Flash at få Barry tilbage, som vrøvler tilfældige udsagn og hele tiden skriver symboler på væggene. Wally går i kamp med samuraien, men bliver besejret. Cisco dechifrerer Barrys skrifter og finder en tilsyneladende meningsløs sætning. I et forsøg på at genvinde Barrys hukommelse giver Iris sig selv til samuraien. Planen virker, og Barry skynder sig væk, redder Iris og besejrer samuraien, som viser sig at være en androide. Caitlin vender tilbage til Team Flash, men det afsløres, at hun har arbejdet for en gangster ved navn Amunet, samtidig med at hun fortsætter med at forhindre Killer Frost-personligheden i at komme frem. "Samuroiden" afsløres at være blevet kontrolleret af en yderst intelligent mand i en kørestol med superkræfter, hvis plan var at lokke Flash ud til sine næste planer.

Da Barry, Joe og Cisco melder sig på et gerningssted, opdager de resterne af en mystisk kode. Cisco præsenterer Barry for en teknologisk avanceret dragt, der skal lette hans aktiviteter. Han afprøver den og forsøger at redde en person fra en afsporet bil, der er kontrolleret af metamennesket Ramsey Deacon. Gypsy ankommer til Jorden-1 for at have en date med Cisco, som er tvunget til at aflyse den for at fokusere på Deacon. Efter et forslag fra Caitlin tilmelder Iris hende og Barry til parterapi for at få styr på deres forhold. Deacon kidnapper et vidne, et tidligere medlem af et teknikerhold, der stjal hans idé med henblik på profit. Barry og Wally tager af sted for at redde ham, men Deacon bruger sine evner til at sende Barrys dragt i uorden. Efter Iris' anvisninger kaster Barry lyn mod sig selv, hvilket kortslutter hans dragt. Han sætter derefter Deacon ud af funktion, som bliver låst inde i meta-fløjen i Iron Heights, hvilket viser sig at være en del af tænkerens plan. Cisco går endelig ud med Gypsy. Barry og Joe undrer sig over, hvordan Deacon fik sine kræfter, da han var fraværende under partikelacceleratorhændelsen, og Barry og Joe får af Deacon at vide, at der er "andre".

I flashbacks observerer Tænkeren Becky Sharpe, en kvinde med tilsyneladende uendeligt uheld, og bestemmer, at hun vil være let at manipulere. I nutiden røver Becky en bank og slipper væk, da Barry glider på kugler. Harry ankommer fra Earth-2 og fortæller Wally, at Jesse har besluttet at slå op med ham for at fokusere på sin selvtægtshåndhævelse. Cisco udleder, at Becky er et metamenneske med magt til at skabe held og lykke, mens hun fremkalder ulykke for andre. Barry indser, at den portal, han brugte for at undslippe Speed Force, udsatte en hel busfuld mennesker, herunder Becky og Deacon, for transformerende mørkt stof. Harry informerer Cisco om, at Jesse har ekskluderet ham fra sit hold til bekæmpelse af kriminalitet på grund af hans attitude. Beckys kræfter ekspanderer ukontrolleret og reaktiverer partikelacceleratoren, hvilket Harry bevidst tillader, hvilket ophæver Beckys kræfter og fører til hendes indespærring. Cisco og Harry identificerer tolv nye metamennesker, der blev skabt i bussen, og sidstnævnte har mistanke om, at en ukendt part har manipuleret begivenhederne omkring Barrys tilbagevenden. Wally beslutter sig for at tage af sted på en rejse for at finde sig selv. Det afsløres, at Thinker spionerer mod S.T.A.R. Labs gennem "Samuroid"-hjelmen. Joe erfarer, at Cecile er gravid.

Gypsys far, Breacher, angriber Cisco og lover at jage og dræbe ham inden for 24 timer, hvilket tillader romancen, hvis han overlever. Team Flash finder ud af, at buschaufføren blev myrdet, og opsporer en anden passager, Ralph Dibny, tidligere korrupt CCPD detektiv, der blev afsløret af Barry og i dag er en berygtet privatdetektiv. Da to bøller angriber Dibny, afsløres det, at han har evnen til at strække sig. Caitlin stabiliserer hans kræfter med et serum. Holdet finder ud af, at Ralph har afpresset borgmester Bellows for utroskab, og det afsløres, at borgmesteren har hyret bøllerne. Barry konfronterer Ralph for hans handlinger, mens sidstnævnte skælder ham ud og hævder at have været en "god betjent". Senere stopper han med at afpresse Bellows, som stadig forsøger at dræbe ham, mens Breacher forveksler førstnævnte med en Plastoid, den art, der tidligere har invaderet Jorden-19, og angriber ham. Cisco griber ind og redder Ralph, som Barry, efter at have afsløret sit alter ego, overtaler til at hjælpe med at anholde en flygtende Bellows. Breacher beundrer Ciscos galanthed og tillader forholdet. Barry rekrutterer Ralph til Team Flash og finder ud af, at en person ved navn DeVoe har instrueret Ralph til at holde øje med Bellows. Barry husker, at både Abra Kadabra og Savitar nævnte DeVoe. I mellemtiden finder Caitlin en besked på sin lejlighedsdør.

Mens det ikke lykkes at spore DeVoe, får Team Flash besøg af Felicity, som deltager i Iris' polterabend. Ralph håner Ciscos planer for Barrys polterabend og tager mændene med til en stripklub, hvor de finder ud af, at Ceciles datter Joanie arbejder. Joe konfronterer hende, som erklærer, at hun kun laver feministisk forskning. Ralph opildner til et slagsmål, hvilket fører til, at mændene bliver anholdt, indtil Harry betaler kaution. Imens kræver Amunets håndhæver, Norvock, Caitlins tilbagevenden og angriber kvinderne, da hun nægter. Killer Frost dukker op og slår ham tilbage, og fortæller senere Iris, at Caitlin accepterede Amunets ansættelse i bytte for midlerne til at kontrollere Frost. Da hun erfarer, at Amunet holder et metamenneske, som hun kalder "Weeper", hvis tårer er et stærkt narkotikum, fanget og har til hensigt at sælge ham, beslutter Iris' gruppe at stoppe hende. Selv om Caitlin nægter at deltage, angriber hun Amunet, da hun ser sine venner i fare. Ved hjælp af en stærk magnet stjæler holdet Amunets metalskår, hvilket gør hende magtesløs. Iris afholder Frost fra at dræbe Amunet, som lover hævn. Begge parter nægter at fortælle hinanden om deres eventyr. Iris beder Caitlin om at være hendes brudepige, mens Joe overtaler Joanie til at fortælle Cecile om sin forskning. DeVoe fanger Weeper.

Barry træner Ralph i at bruge sine evner, og Cisco laver en strækbar dragt til ham. Et andet bus-metamenneske, en Lakota Sioux-indfødt ved navn Mina Chayton, der kan animere statuer, begynder at angribe Central City & stjæle stykker af en Black Bison halskæde, som hun hævder tilhører hendes stamme. Da Barry og Ralph indhenter hende, angriber hun Barry med en hulemandsstatue og forsøger at stikke af. Ralph vælger at stoppe hende, men en lille pige bliver såret i processen. Ralph fortryder sine handlinger, men bliver trøstet af Barry. Chayton undslipper CCPD og går efter det sidste halskæde-stykke, der opbevares på museet. Da Barry og Ralph konfronterer hende, vækker hun et dinosaurskelet til live. Barry anholder Chayton, mens Ralph redder en sikkerhedsvagt fra skelettet. Senere afslører Ralph, at han sendte halskæden tilbage til Chaytons stamme, inden han besøger den lille pige på hospitalet og bruger sine evner til at underholde hende. I mellemtiden arbejder Harry, der forsøger at få venner, sammen med sine dobbeltgængere fra alternative jordkloder, The Council of Wells, for at få venner. De finder ud af, at DeVoe er en mand ved navn Clifford DeVoe. Barry og Joe tager til DeVoes hus for at finde ud af, at han er en midaldrende mand i en kørestol.

Barry og Joe afhører DeVoe og hans kone for at forsøge at få flere oplysninger. I flashbacks bygger DeVoe og hans kone en tænkehætte for at forbedre hans hjernekapacitet og driver den gennem partikelacceleratoreksplosionen. DeVoes øgede hjernekapacitet fremskynder hans amyotrofiske lateralsklerose, hvilket tvinger hans kone til at bygge ham en særlig stol for at holde ham i live. Barry opdager kameraet i det samuroide hoved og tager til DeVoes hus, hvor han undgår med nød og næppe at blive fanget af DeVoes kone. Barry konfronterer senere DeVoe, som afslører sin sande identitet, hvilket får Cisco til at døbt ham "The Thinker". Wally vender tilbage til Team Flash fra Blue Valley.

Barry, Oliver, Sara, Alex, Martin og Jax vågner op i en nazistisk koncentrationslejr på Earth-X iført strømdæmpere. Den ankommende SS Sturmbannführer viser sig at være Earth-X-dobbeltgængeren af Quentin Lance, som planlægger at henrette dem, men de bliver reddet af Citizen Cold (Earth-X-dobbeltgængeren af Leonard Snart) og Ray Terrill. Snart og Terrill tager dem med til Freedom Fighters' hovedkvarter, hvor holdet møder modstandsbevægelsens leder, general Schott (Winn Schotts Earth-X-dobbeltgænger). De finder ud af, at den eneste vej tilbage til Jorden-1 er gennem en tidsmæssig port i et forskningsanlæg, som Schott planlægger at sprænge i luften for at strande Dark Arrow (Olivers Earth-X-dobbeltgænger) på Jorden-1. Oliver forklæder sig som Dark Arrow for at infiltrere anlægget og opdager, at den nazistiske dommedagsanordning mod parallelle jordkloder er et militariseret tidsskib kaldet Wellenreiter. Barry og Ray kæmper mod Freedom Fighters' Red Tornado for at forhindre den i at ødelægge portalen, mens resten af holdet går ind i anlægget for at genaktivere dets portal, hvor Stein bliver skudt og alvorligt såret. På Jorden-1 forbereder Eobard Thawne sig på at udføre en operation på Kara for at redde Overgirl. Felicity og Iris forsøger at stoppe ham, men bliver taget til fange.

Mens Barry er ude at julehandle, bliver han overfaldet og kidnappet af DeVoe, mens Caitlin bliver kidnappet fra Jitters af Amunet. Iris hævder, at de er nødt til at lede efter dem begge, på trods af at Harry hævder, at de ikke har nok tid og ressourcer, og at de kun har råd til at lede efter den ene. Barry bliver tilbageholdt i DeVoes hule. Caitlin tvinges af Amunet til at udføre en operation på et metamenneske ved navn Dominic Lanse, som kan læse tanker. De forsøger at flygte, men Amunet blokerer deres udgang. Det lykkes Caitlin kortvarigt at uskadeliggøre Amunet, og hun og Dominic flygter fra den bygning, de holdes fanget i. Da de kommer udenfor, bliver de reddet af Cisco og Ralph, da Iris har valgt at fokusere på at finde Caitlin. Det lykkes Barry at flygte fra DeVoe. Team Flash fejrer jul i Wests hus, og Dominic slutter sig til dem. Barry får en sikkerhedsalarm fra sin lejlighed. Da han ankommer, modtager han et telefonopkald fra Dominic, som afslører, at Amunet har kidnappet Dominic igen, og DeVoe har overført sin bevidsthed til Dominics krop. Barry opdager DeVoes oprindelige krop død på gulvet i sin lejlighed, og det går op for ham, at DeVoe har lagt en fælde for hans "mord"; politiet ankommer, og Barry lader sig anholde, da han ikke ønsker at forlade Iris igen.

Barry står for retten for mordet på Clifford DeVoe, og Cecile repræsenterer ham. Cisco og Joe er nødt til at tage af sted under retssagen på grund af en metaundersøgelse, hvor en meta fik folk til at kollapse. Singh afslører over for Joe, at han skal optræde som vidne for anklagemyndigheden mod Barry. Metaen bliver til sidst afsløret som Neil Borman, der er en meta, som producerer stråling, hvilket forårsager sygdommen og kollapsene. Barry tager sig af ham, men er dårligt rustet til at håndtere situationen. Cisco og Killer Frost rejser til stedet, hvor Caitlin forsøger at fryse Borman ned, som hurtigt optøes og sætter Caitlin ud af stand til at handle. Barry skaber et vakuumforsegling omkring Borman for at inddæmme strålingen, og Cisco transporterer strålingen til den døde Earth-15, dræner metaen og besejrer ham. Barry bliver i sidste ende fundet skyldig af juryen og idømmes livsvarigt fængsel.

Barry bruger sin hurtighed til i hemmelighed at hjælpe vagterne med at holde de andre indsatte under et fængselsoprør. Han bliver også venner med Dave Ratchet, sin fars tidligere cellekammerat. Den næste dag møder Barry Axel Walker, som senere blev brudt ud af fængslet af sin mor Zoey Clark, hans fars tidligere makker Prank. Axel udfordrer Ralph ved at true med at skabe kaos i byen. Ralph forsøger at stoppe ham, men bliver såret af Axel og bliver evakueret af Cisco. Ralph sniger sig ind i fængslet for at tale med Barry om, hvor bange han er. Barry forsikrer ham om, at det at være en helt ikke handler om ikke at være bange, men om at have evnen til at hæve sig over sin frygt. Cisco og Caitlin går ud for at redde gidslerne, men bliver fanget af Axel og Zoey, som har til hensigt at dræbe dem. Ralph ankommer og forsøger at beskytte de to mod en syrebruser, indtil det lykkes Wells at hacke sig ind i brusesystemet for at neutralisere syreindholdet. Iris besøger Barry i fængslet, hvor de bekræfter deres kærlighed til hinanden på ny. Ralph og Cisco går ud for at få kaffe, hvor de møder den ophidsede pige fra brylluppet. Pigen skriver i sin dagbog, hvor hun ser ud til at skrive på det sprog, som Barry brugte, da han kom ud af Speed Force.

Cecile udvikler telepatiske evner som følge af sin graviditet, kombineret med hvilende mørkt stof i hendes celler, hvilket Caitlin forsikrer hende om, at det skulle være midlertidigt. I fængslet finder Barry ud af, at Ratchet er uskyldig i et røveri-mord, der i virkeligheden blev begået af Sylbert Rundine femten år tidligere. Barry beder holdet om at undersøge sagen nærmere. Rundine viser sig at være en busmeta med evnen til at krympe og forstørre genstande, og han krymper Cisco og Ralph, mens han flygter. Harrys forsøg på at helbrede ham går galt, og Caitlin bestemmer, at hvis de ikke bliver forstørret igen inden for et vist tidsrum, vil deres kroppe eksplodere. Holdet konfronterer Rundine på et lager, hvor Harry narrer ham til at gøre Ralph og Cisco større igen. Rundine bliver arresteret, men nægter at tilstå den tidligere forbrydelse. Barry opdager, at selv hvis Ratchet blev løsladt, ville han være lige så ulykkelig i byen som i fængslet; han ønsker at bo i en afsidesliggende kinesisk landsby kaldet Jiaju, men frygter, at han aldrig vil komme dertil. Barry bruger så sin hurtighed til at tage Ratchet med til Jiaju, hvor han kan udleve sin drøm. Efter at have opdaget, at Barry er Flash, låser fængslets fængselsinspektør Gregory Wolfe Barry inde i sin private metamenneske fløj med den hensigt at sælge ham til Amunet.

Wolfe planlægger at sælge Barry og de fængslede busmetaer (Ramsey Deacon, Becky Sharpe, Mina Chaytan og Sylbert Rundine) til Amunet, så de planlægger at flygte. Cecile opdager Wolfes planer efter at have læst hans tanker. Ralph møder en tidligere kollega, og hans negative interaktion med ham får ham til at opdage, at han kan skifte skikkelse. Hans manglende beherskelse af den nye evne forhindrer ham i at forsøge at forpurre Amunets aftale med Wolfe. Barry hjælper metaerne med at undslippe kraftdæmperne, men de bliver trængt op i et hjørne af Wolfe og Amunet. DeVoe ankommer og bruger igen sin stol til at trække metaernes evner ud, inden han overfører sit sind til Sharpes krop. Derefter knuser han Wolfes kranie, mens Marlize ser på i rædsel; Amunet flygter. Ralph bruger sin formskifteevne til at optræde som den oprindelige DeVoe ved Barrys appel og hævder, at han var bevidstløs på Barrys loft, men ikke død, hvilket renser Barrys navn. Team Flash indser, at DeVoe kun stjæler kræfter fra metahumaner, der var i bussen, da bølgen af mørkt stof blev udløst, hvilket betyder, at han sandsynligvis også vil gå efter Ralph. Tilbage i DeVoes hus fortsætter deres ægteskab med at gå i forfald, og DeVoe bedøver sin kone med Weeper's tårer for at bevare hendes hengivenhed over for ham.

Barry bliver sat på orlov på ubestemt tid hos CCPD på grund af hans forbindelse med DeVoe-sagen. Holdet møder et andet bus metamenneske ved navn Izzy med lydbølgeevner, forstærket af hendes violin. Det lykkes hende at bruge sine evner, da DeVoe (i Sharpe's krop) kommer for at hente hende. Barry og Ralph hjælper med at træne Izzy til at forfine sine evner, hvilket viser sig at være svært, da hun kommer til skade. Til sidst dukker DeVoe op igen og bruger Dominics og Beckys evner til at få Barry til at få en hjerneaneurisme, mens han bruger Rundines evner til at gøre Ralph uarbejdsdygtig. DeVoe bruger derefter endnu en gang stolen til at overføre sit sind til Izzys krop og flygter. Både Ralph og Barry trøster hinanden over deres respektive tab: Barry bliver fyret fra politiet, og Ralph mister Izzy til DeVoe. Disse tab forstærker både Barrys og Ralphs beslutsomhed til at fælde DeVoe og redde de tre tilbageværende metaer.

Jesse kommer til Jorden-1 for at få en snak med sin far. Øko-terroristen Veronica Dale udløser en atombombe, som Barry forsøger at stoppe og går ind i en form for superspeed, kendt som Flashtime, hvor alt er frosset. Bomben er dog allerede detoneret, og han og Jesse kan ikke stoppe den eller redde alle med superspeed. Jay Garrick kommer fra Earth-3 for at hjælpe, men de er stadig ikke i stand til at stoppe den. Barry bliver i Flashtime i timevis og bringer hver af sine venner ind i den i et forsøg på at finde en løsning; de diskuterer muligheder som at fryse den eller sende den til en anden jord, men ingen af disse løsninger viser sig at være brugbare. Til sidst giver Iris ham ideen om at hente Quark-sfæren fra Speed Force for at sende et lynnedslag gennem bomben, nok til at sætte den ud af funktion. Barry gør det, og kaster kuglen tilbage i hastighedskraften og redder Central City. Jay indrømmer, at han går på pension og vil træne en ny "kvindelig" speedster. Jesse og Jay vender tilbage til deres jordkloder, og Caitlin og Wells går ud og drikker kaffe, hvor de møder den mystiske pige.

Et metamenneske med ildkræfter forsøger at røve Central Citys bank. En anden busmeta ved navn Matthew Kim rører ved metamennesket, hvilket får hans kræfter til at blive overført til et andet individ. Da Joe, Iris og Barry dukker op for at stille Kim et par spørgsmål, kommer Barry og Iris i kontakt med Kim, hvilket får Barry til at miste sin fart og Iris til at få superfart. Inspireret af Thawne planlægger Harry at bygge sin egen tænkehætte for at overliste DeVoe. Med deres roller byttet om bliver Iris Central Citys helte-speedster, mens Barry må lære at agere som teamleder. Det nye metamenneske kræver penge og terroriserer byen med sine ildkræfter. Ved hjælp af Wells' tænkehætte får teamet en idé om, at Iris kan skabe en tidevandsbølge, der ophæver flammerne og besejrer metamanden. Tilbage på S.T.A.R. Labs berører Kim Iris og Barry igen og genopretter Flashs hastighed. Derhjemme indrømmer Iris, at selv om hun nød at have superspeed, har Central City brug for det lys, som Barry var, og hun er glad for at være teamleder. Wells bruger endnu en gang sin tænkehue og bestemmer, at de to sidste busmetaer er Janet Petty og Edwin Gauss.

Barry og Ralph træner for at besejre DeVoe, og Barry bliver irriteret over Ralphs tilsyneladende manglende evne til at være seriøs. Det lykkes holdet at finde en anden busmeta, Janet Petty. Da Barry og Ralph konfronterer hende, viser det sig, at Petty kan manipulere en persons tyngdekraft, hvilket hun demonstrerer på Barry. Barry frygter endnu en gang, at Ralph ikke tager tingene alvorligt, og nægter at arbejde sammen med ham. Ralph afslører, at hans komiske attitude skyldes en vanskelig barndom, hvor hans far forlod ham, hvilket får ham til at lave vittigheder, når han er bange eller under pres. Barry giver efter, og de tager af sted for at stoppe Janet ved en gallafest. Janet bruger sine kræfter på Barry, hvilket får ham til at svæve op i atmosfæren. Barry fortæller holdet, at de skal stole på, at Ralph kan improvisere. Ralph tilbageholder Janet, hvorefter han bliver til en kæmpe airbag, så Barry kan lande sikkert. DeVoes kone opdager, at han har bedøvet hende, så hun vil fortsætte med at hjælpe ham. Breacher kommer til Jorden-1 for at bede Cisco om hjælp, da nogle af hans kræfter har svigtet. Harry tager tænkehætten med til Thawnes tidsboks for at genoplade den og aktiverer Gideon.

Caitlin afslører for Iris, at Killer Frost aktiveres af hendes binyrebarkhinde, og hun arbejder på en måde at adskille dem på. Harry finder på et stemmegaffelvåben, der efterligner Izzys evner, for at besejre DeVoe. Ralph afslører over for Barry, at han ikke er bange for at miste sit eget liv, men for at Team Flash mister deres liv, da han betragter dem som familie. Wells viser sig at være afhængig af Thinking Cap, hvilket Joe hjælper ham med at håndtere. Ralph tager gaflen, med den hensigt at tage med Edwin for at dræbe DeVoe, hvilket Barry argumenterer imod. Til sidst lykkes det DeVoe at overtage Edwins sind og tager også Janet Pettys og Matthew Kims evner, inden han overfører sit sind til Ralphs krop. Holdet forsøger at stoppe ham, men DeVoe gør dem uarbejdsdygtige og ændrer Caitlins DNA, fjerner den mørke materie og Killer Frost, inden han forlader stedet. Tilbage i sin hule bruger DeVoe Ralphs morphing-egenskaber til at forvandle sig tilbage til sin oprindelige form, mens han og Marlize planlægger deres næste træk for at ødelægge Team Flash.

Da DeVoe går videre med sine planer, beslutter Team Flash sig for at sikre Neil Borman. Barry og Cisco rejser til Earth-X for at rekruttere Leo Snart som backup, men bliver forfulgt til Earth-1 af Earth-X-dobbeltgængeren af Laurel Lance. Team Flash planlægger at levere Borman til et sikkert ARGUS-anlæg ved hjælp af en dragt til at begrænse strålingen, med Snart ved hånden, hvis Borman skulle gå amok. Snart indvilliger i at hjælpe, men hævder, at han kun kan blive i 24 timer, da han skal giftes med Ray Terrill. DeVoe forsøger at afbryde overførslen, men han og Team Flash bliver yderligere overfaldet af Earth-X Laurel, som kidnapper Caitlin, Borman og Joe og holder dem fanget på CCPD. Snart hører om Ralph og overtaler Barry til at tillade sig selv at sørge over sine faldne allierede, hvilket Barry til sidst gør, hvilket giver ham styrke til at besejre Laurel. Lyla overfører Borman til et andet sted, og Leo vender tilbage til Earth-X. Cisco og Wells udtænker en plan for at styrke Wells' tænkehætte. DeVoe går mere ind i sit "gudskompleks"; han erklærer, at menneskelige følelser er en svaghed, hvilket får Marlize til at tvivle på ham.

Harry afslører over for holdet, at den mængde mørkt stof, han brugte med Thinking Cap, forårsagede hjerneskader. Cisco, Gypsy, Barry og Caitlin kæmper mod Marlize og DeVoe, da de får fat i de computere, der er nødvendige for at drive oplysningsmaskinen. Flashbacks afslører delvist, hvorfor Marlize følger DeVoe: Hun var en humanitær arbejder i Kenya, som skabte en vandrensningsmaskine til en landsbyboer, men da krigsherrerne fandt ud af det, angreb de og dræbte alle. Marlize bønfalder DeVoe, da han begynder at kvæle Gypsy; hun beslutter sig senere for at forlade ham og indkapsler hans stol i et kraftfelt, så DeVoe ikke kan forhindre hende i at forlade lommedimensionen. Holdet indser, at DeVoe planlægger at bruge oplysningsmaskinen til at sende mørkt stof mod Jorden, så hele menneskeheden bliver tilbageført til en forenklet tilstand, svarende til det, som Harry har med at gøre. Den mystiske pige bringer en gave med til Cecile og Joes baby shower og løber væk ved hjælp af speedster-evnerne, efter at hun hurtigt er gået.

Cisco samler et råd af Harrisons for at forsøge at finde en måde at stoppe Harrys intelligenstab på. Team Flash går modvilligt til Amunet for at få hjælp og møder hendes efterfølger Norvok i processen, selv om Barry insisterer på, at Amunet ikke må dræbe. Holdet får til sidst en bombe lavet af Amunets metal, som vil kunne ødelægge en af DeVoes satellitter, og det lykkes Harry at regne ud, at DeVoes plan måske er ved at ændre sig, fordi Marlize ikke længere er sammen med ham. Iris offentliggør en artikel, der afslører DeVoes plan, og indbyggerne i Central City begynder at rapportere observationer af DeVoe, hvilket Iris mener vil hæmme hans evne til at forblive uopdaget.

DeVoe infiltrerer A.R.G.U.S.-anlægget med Fallout ved at udgive sig for at være John Diggle og dræber det meste af sikkerheden, bortset fra et par gidsler; overlader og dræber Fallout for at blive et atombatteri til satellitterne. Barry løber til Star City og bringer John tilbage for at afsløre placeringen af anlægget. Caitlin og Cisco beder Barry om at træne dem i Flashtime, så de kan redde gidslerne, og Barry kan følge DeVoe gennem bruddet, før det lukker sig. I de sidste stadier af graviditeten får Ceciles telepati hende til at overtage personligheden og tankerne hos alle i nærheden. Harry og Iris sporer Marlize til London og bruger den sidste ekstrapolator for at komme dertil. Caitlin og Cisco er i stand til at redde gidslerne. Caitlin søger i sit sind efter Killer Frost og får Cisco til at få hende til at vibrere ind i en undertrykt erindring om en ulykke i barndommen; Killer Frost var allerede en del af Caitlin årtier før partikelacceleratoren havde skabt nogen metas. Det lykkes Barry at følge DeVoe gennem bruddet og ødelægger en af satellitterne med Amunets bombe. DeVoe overtager kontrollen over S.T.A.R. Labs og bruger dens satellit til at erstatte den ødelagte satellit. Han iværksætter oplysningsprotokollen i tidskammeret.

Efter at oplysningen begynder, slutter Marlize sig til Team Flash, da Cecile går i fødsel. Marlize bruger Ceciles kræfter til at sende Barry ind i DeVoes bevidsthed for at finde det gode, der er tilbage i ham. Barry finder Ralph i live i DeVoes bevidsthed, og sammen finder de den "gode" DeVoe død. DeVoe forsøger at forhindre dem i at nå frem til nexusen i hans sind, da han følger Team Flash til en lommedimension. I sin bevidsthed multiplicerer DeVoe sig selv for at bekæmpe Barry og Ralph, mens han nedlægger Team Flash. Barry og Ralph når frem til nexusen; Barry vågner op i den virkelige verden, og Ralph genvinder sin krop, netop som DeVoe ville dræbe Cecile. Han dukker dog op igen som et hologram gennem sin stol, indtil Marlize ødelægger den. Barry, Cisco og Ralph beskytter civile mod de nedfaldende satellitter, og den mystiske pige hjælper Barry med at ødelægge den sidste satellit. Harrys hjerne nulstilles, men bliver for det meste genoprettet af Marlize; han beslutter sig for at vende tilbage til Jorden-2 for at være sammen med Jesse. Team Flash fejrer DeVoes nederlag med Wally (som er vendt tilbage fra Legends) og Ceciles nyfødte datter Jenna. Den mystiske pige ankommer og afslører sig selv som Barry og Iris' datter fra fremtiden, Nora; hun hævder at have begået "en stor, stor fejltagelse".

Iris has been aiding Team Flash in Central City for six months, but refuses to grieve Barry. A flying samurai with superpowers appears in Central City, threatening to destroy the city if the real Flash does not face him. Cisco reveals he has formulated a way to bring back Barry without destabilizing the Speed Force and tracks down Caitlin for help, but is forbidden by Iris to bring Barry back. Against Iris' orders, Team Flash successfully returns Barry, who rambles random statements and continually writes symbols on the walls. Wally engages the samurai, but is defeated. Cisco deciphers Barry's writings and finds an apparently meaningless sentence. In an attempt to recover Barry's memories, Iris gives herself up to the samurai. The plan works and Barry speeds away, rescuing Iris and defeating the samurai, who is revealed to be an android. Caitlin rejoins Team Flash, but is revealed to have been working for a mobster called Amunet, while also continuing to prevent the Killer Frost personality from emerging. The "Samuroid" is revealed to have been controlled by a supremely intelligent man in a superpowered wheelchair, whose plan was to draw out the Flash for his next schemes.

He tests it out, trying to save someone from a haywire car controlled by metahuman Ramsey Deacon. Gypsy arrives on Earth-1 for a date with Cisco, who is forced to cancel it so as to focus on Deacon. Acting on a suggestion from Caitlin, Iris signs her and Barry up for couples therapy to sort out their relationship. Deacon kidnaps a witness, a former member of a tech team that stole his idea for profit. Barry and Wally go to save him, but Deacon uses his abilities to send Barry's suit haywire. On Iris' instruction, Barry throws lightning at himself, shorting out his suit. He then incapacitates Deacon, who is locked up in the meta wing of Iron Heights, revealed to be part of the Thinker's plan. Cisco finally goes out with Gypsy.

In flashbacks, the Thinker observes Becky Sharpe, a woman with seemingly unending bad luck, and determines that she will be easily manipulated. In the present, Becky robs a bank and gets away when Barry slips on marbles. Harry arrives from Earth-2 and tells Wally that Jesse has decided to break up with him in order to focus on her vigilantism. Cisco deduces that Becky is a metahuman with the power of favorable luck while inducing misfortune to others. Barry realizes that the portal he used to escape the Speed Force exposed an entire busload of people, including Becky and Deacon, to transformative dark matter. Harry informs Cisco that Jesse has expelled him from her crime-fighting team due to his attitude. Becky's powers expand out of control, reactivating the particle accelerator, which Harry deliberately allows, nullifying Becky's powers and leading to her incarceration. Cisco and Harry identify twelve new metahumans created on the bus and the latter suspects that an unknown party has manipulated the events surrounding Barry's return. Wally decides to leave on a journey to find himself. The Thinker is revealed to be spying on S.T.A.R. Labs through the "Samuroid" helmet. Joe learns Cecile is pregnant.

Ralph sneaks into the prison to talk to Barry about how scared he is. Barry reassures him that being a hero isn't about not being scared, but about having the ability to rise above your fear. Cisco and Caitlin go to rescue the hostages, but get captured by Axel and Zoey, who intend to kill them. Ralph arrives, and attempts to shield the two from an acid shower, until Wells manages to hack into the shower system to neutralize its acidity.

Cecile develops telepathic abilities as a result of her pregnancy, combined with dormant dark matter in her cells, which Caitlin assures her should be temporary. In prison, Barry learns that Ratchet is innocent of a robbery-homicide that was actually committed by Sylbert Rundine fifteen years prior. Barry asks the team to look into the case. Rundine turns out to be a bus meta with the ability to shrink and enlarge objects, and he shrinks Cisco and Ralph while escaping. Harry's attempted cure backfires, and Caitlin determines that if they are not re-enlarged within a certain period of time, their bodies will explode. The team confronts Rundine at a warehouse, where Harry tricks him into re-enlarging Ralph and Cisco. Rundine is arrested, but refuses to confess to the earlier crime. Barry gathers that even if Ratchet went free, he would be as unhappy in the city as he is in prison; he wishes to live in a secluded Chinese village called Jiaju, but fears he will never get there. Barry then uses his speed to take Ratchet to Jiaju, where he can live out his dream. After discovering Barry is the Flash, the prison's warden, Gregory Wolfe, locks Barry in his private metahuman wing, intending to sell him to Amunet.

Cecile discovers Wolfe's plans after reading his mind. Ralph encounters a former colleague and his negative interaction with him prompts the discovery that he can shapeshift. His lack of mastery of the new ability prevents his attempt to foil Amunet's deal with Wolfe. Barry helps the metas escape the power dampeners, but they are cornered by Wolfe and Amunet. DeVoe arrives and again uses his chair to extract the metas' abilities, before transferring his mind into Sharpe's body. He then crushes Wolfe's skull as Marlize looks on in horror; Amunet flees. Ralph uses his shapeshifting ability to appear as the original DeVoe at Barry's appeal, claiming that he was unconscious at Barry's loft but not dead, which clears Barry's name. Team Flash realizes that DeVoe is only stealing powers from metahumans who were on the bus when the dark matter wave was unleashed, which means he will likely target Ralph as well. Back at the DeVoes' house, their marriage continues to deteriorate, and DeVoe drugs his wife with the Weeper's tears to maintain her devotion towards him.

DeVoe then once again uses the chair to transfer his mind into Izzy's body and escapes. Both Ralph and Barry comfort each other over their respective losses: Barry being let go from the police force and Ralph losing Izzy to DeVoe.

Barry, Cisco, Iris and Harry attempt to trigger Killer Frost's powers in Caitlin, but do not succeed. Harry reveals to the team that the amount of dark matter he used with the Thinking Cap caused brain damage. Cisco, Gypsy, Barry and Caitlin fight Marlize and DeVoe when they acquire the computers required to power the Enlightenment Machine. Flashbacks reveal partially why Marlize follows DeVoe: she was a humanitarian worker in Kenya who created a water purifier for a villager, but when warlords found out about it, they attacked and killed everyone. Marlize pleads with DeVoe when he begins choking Gypsy; she later decides to leave him, encasing his chair in a force-field so DeVoe cannot stop her from leaving the pocket dimension. The team realizes that DeVoe plans to use the Enlightenment Machine to launch dark matter towards Earth, reverting all of humanity into a simplified state, similar to what Harry is dealing with. The mysterious girl brings a gift to Cecile and Joe's baby shower and, after leaving quickly, runs away using speedster abilities.

Cisco assembles a Council of Harrisons to try and come up with a way of stopping Harry's intelligence loss. Team Flash reluctantly go to Amunet for help, encountering her successor Norvok in the process, though Barry insists Amunet must not kill. The team is eventually given a bomb made from Amunet's metal which will be capable of destroying one of DeVoe's satellites, and Harry manages to work out that DeVoe's plan might be changing because Marlize is no longer with him. Iris posts an article revealing DeVoe's plan and the residents of Central City begin reporting DeVoe sightings, which Iris believes will hamper his ability to remain undetected.

DeVoe infiltrates the A.R.G.U.S. facility holding Fallout by impersonating John Diggle and kills most of the security, except for a few hostages; overcharging and killing Fallout to be a nuclear battery for the satellites. Barry runs to Star City and brings back John to reveal the location of the facility. Caitlin and Cisco ask Barry to train them in Flashtime so that they can save the hostages and Barry can follow DeVoe through the breach before it closes. In the last stages of pregnancy, Cecile's telepathy causes her to take on the personality and thoughts of anyone nearby. Harry and Iris track Marlize to London, and use the last extrapolator to get there. Caitlin and Cisco are able to rescue the hostages. Searching her mind for Killer Frost, Catlin has Cisco vibe her into a repressed memory of a childhood accident; Killer Frost was already part of Caitlin decades before the particle accelerator had created any metas. Barry manages to follow DeVoe through the breach and destroys one of the satellites with Amunet's bomb. DeVoe takes control of S.T.A.R. Labs and uses its satellite to replace the one destroyed. He initiates the Enlightenment protocol in the time vault.

After the Enlightenment begins, Marlize joins Team Flash as Cecile goes into labor. Marlize uses Cecile's powers to send Barry into DeVoe's consciousness to find the good left in him. Barry finds Ralph alive in DeVoe's consciousness and together they find the "good" DeVoe dead. DeVoe attempts to keep them from reaching the nexus of his mind, as he follows Team Flash to a pocket dimension. In his consciousness, DeVoe multiplies himself to fight Barry and Ralph as he takes down Team Flash. Barry and Ralph make it to the nexus; Barry wakes up in the real world and Ralph reclaims his body just as DeVoe was going to kill Cecile. He reappears, though, as a hologram through his chair until Marlize destroys it. Barry, Cisco and Ralph shield civilians from the falling satellites and the mysterious girl helps Barry destroy the last one. Harry's brain resets but is mostly restored by Marlize; he decides to return to Earth-2 to be with Jesse. Team Flash celebrates DeVoe's defeat with Wally (who returned from the Legends) and Cecile's newborn daughter Jenna. The mysterious girl arrives to reveal herself as Barry and Iris' daughter from the future, Nora; she claims to have made "a big, big mistake".
