In this documentary thriller, when police raid a house in a city north of New York City, 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 the slayer's identity, the identity of his victims, and where he could possibly have gone. But repeated viewings of the material reveals 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.
