After a team profiler is believed to be the latest victim of a serial killer, the squad is surprised by the new replacement, a rookie agent without much profiling experience. Squad supervisor Virgil "Web" Webster has a feeling about this rookie. He senses that Agent Rebecca Locke has a "gift" and that is why he chose her for his team. In short time the other team members can't help but be impressed with her too.
Rebecca and the team probe the disappearance of the Anderson and Presley families who went missing in the Angeles National Forest along Highway 39. The team quickly arrest Karl Robie Jr. but on the way to find the Presley family the helicopter carrying Danny, Rebecca and Karl crashes and so ensues a frantic bid to find Rebecca before Karl does. Rebecca is haunted by visions of her past abduction by Pony Man.
The team gets a tape of a snuff movie where a young girl is assassinated. They believe the tape was not tampered with and it's not a fake contrary to most snuff movies. They match the face of the girl on the tape to a missing girl report entered by Arlen Dallas. On instinct, Rebecca asks Carter to reconstruct the face of the girl at different ages. It is discovered that she has been spotted on hundreds of child pornography materials at different ages.
