Jack is shot by a blank and falls out onto the front steps of Helen’s house. Regaining his footing, Jack walks back into the house only to be ambushed by a hiding Helen. Returning to the station, Laura is confronted by Amy’s father Albert, and is forced at gunpoint to look for Jack. After spending the night drinking and watching videos from Amy’s last birthday party, Albert intends to force Jack to find his daughter, or he’ll kill Laura. Jack awakes, only to find himself tied up in a dining room full of people. In horror, Jack realizes that the dining room is populated not by people, but the disfigured bodies of the missing victims, including Amy and Darby. When Helen’s husband and daughter were killed in the Shallow Valley dam accident, she was driven mad and plotted a twisted revenge on those who built the dam. Helen stalked the spouses and children of those involved and one by one, whenever they were alone, would sedate them with an injection and drag them out into the woods. Helen would strip her victims naked and chain them to a tree, slicing parts of their bodies open once they had regained consciousness. Once they were drained of their blood, Helen would stitch her victims closed, dress their bodies, and take them back to her home to further disfigure them in her dining room. Distracted by Laura and Albert's sudden arrival, Helen rushes outside and opens fire. Enraged at seeing Amy’s father die, the bloody boy wails and advances towards Helen. As the gun goes off, Helen and the boy's blood connects, revealing to him that she’s the killer. Panicked, Helen fails to take Laura hostage and flees into the woods. Freeing himself from his bindings, Jack rushes outside and gives chase. Once alone, Helen turns to shoot Jack, only to find the bloody boy standing between them. Jack watches on as the boy slits Helen’s neck vertical, reaches inside and begins strangling her. Jack leaves Helen to suffer her fate, ignoring her feeble attempts at screaming for his help. Just as he did before with Jack, the boy forces Helen to relives the deaths of her victims, mentally and also physically, again and again until she finally dies. The next morning, Jack, Laura, and Russell bury Amy and the other victims. The three depart from Shallow Valley, unsure of everything that’s happened
