"Redux" is the two-part fifth season premiere of the science fiction television series The X-Files. "Redux" first aired on November 2, 1997, on Fox in the United States, with "Redux II" airing on November 9. Both episodes subsequently aired in the United Kingdom and Ireland. Both episodes were written by series creator Chris Carter, with "Redux" directed by R. W. Goodwin and "Redux II" helmed by Kim Manners. "Redux" became the second-most-watched episode ever broadcast, earning more than 27 million viewers in the United States alone. The first part of the episode received mixed to negative reviews, whereas the second part received mixed to positive reviews from critics. The show centers on FBI special agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson) who work on cases linked to the paranormal, called X-files.

"Redux" follows Scully, who helps Mulder to fake his own death in an effort to discover which members of the FBI they can trust before the agents individually search for an answer to Scully's cancer. "Redux II" continues immediately afterwards with Scully hospitalized, and Mulder is offered a deal to ally with the Cigarette Smoking Man (William B. Davis). "Redux", being a part of a three-part episode arc, became a storyline milestone for the series. It marked the first episode in which Fox Mulder loses his belief in extraterrestrial life and the revelation that someone inside the FBI has tried to discredit Mulder and Scully's work on the X-files. When writing the episode, Carter wanted to tie up loose ends from the previous seasons. Despite being the first two episodes of the season aired, they were the second and third episodes produced, the first being "Unusual Suspects", which explained the origins of The Lone Gunmen.

Professor Arlinsky, the team's leader, sends ice core samples containing presumably alien DNA to Fox Mulder (David Duchovny). Both Mulder and Dana Scully (Gillian Anderson) eventually meet Michael Kritschgau (John Finn), a Defense Department employee who claims that everything Mulder thinks he knows about aliens is a lie. Kritschgau tells Mulder that his sister Samantha's abduction was fabricated, that all evidence of alien biology are merely scientific anomalies, and that the alien body discovered in Canada was fake. He also claims that the
