What Happens, Part by Part (Contains Spoilers)
The arrest
The body of young Frank Peterson is found in a park. Witnesses saw Terry Maitland with blood on his clothes, and his fingerprints and DNA are everywhere. Detective Ralph Anderson, angry because his own son was coached by Terry, arrests him in front of a crowd at a Little League game. Terry insists he is innocent.
The alibi
Terry's lawyer, Howie Gold, shows that Terry was at a teachers' conference in another city at the time of the killing. There are witnesses and even a video of him asking a question. How could he be in two places at once? Before the trial, Terry is shot dead outside the courthouse by Frank's brother. He dies saying he did not do it.
Doubt
Ralph is haunted by Terry's words. The case falls apart, and more tragedy follows for both the Peterson and Maitland families. Howie hires Holly Gibney, a private investigator, to look into Terry's trip. She finds a similar case in Ohio, where another innocent man was blamed for a child's murder after visiting the same place as Terry.
The Outsider
Holly realizes that a creature can take the appearance of people, using their DNA, and feeds on grief and pain. She links it to the Mexican legend of El Cuco. Ralph, a man who believes only in facts, struggles to accept the idea, but the evidence leaves no other explanation. The creature is now taking on the appearance of a new man in Texas.
The cave
Ralph, Holly and a small team travel to Texas and track the creature to a cave known as Marysville Hole. A violent confrontation leaves several people dead. Holly destroys the creature with a sock filled with ball bearings. Ralph returns home changed, ready to accept that some things are beyond explanation.
