The episode describes the trial of Richard Allen, who is accused of killing two teenage girls in Delphi, Indiana. Allen allegedly confessed to the crime in multiple phone calls to his wife and to corrections officers and a psychologist. However, his mental state has been brought into question, with a psychologist testifying that Allen suffers from "situational psychosis." The trial has also focused on identifying the voice of the man on Libby German's phone recording, with witnesses identifying Allen as the "bridge guy." The defense has argued that police did not investigate other possible suspects and that Allen's mental illness could have affected his confessions.
