When police raid a house in a city north of New York, they discover a profoundly disturbing record of one man's ugly crimes. Investigators find over 800 videotapes shot by the killer which present a visual record of his murders in all their horrifying details. Both state and federal law enforcement teams sift through the gruesome images, looking for clues of his identity, the identity of his victims, and where he could have gone. Repeated viewings of the materials reveal little beyond the terrible facts of the crimes, and as the authorities comb through the madman's images, they find the tapes have had a disquieting effect on them.
