A sadistic serial killer holds Los Angeles in the grip of unspeakable fear in this hard-hitting action-thriller. Rejected from the police force on psychological grounds, Buck Taylor (Judd Nelson) exacts revenge by committing a string of brutal murders and taunting the LAPD. The only clues are pages torn from a telephone book and victims who appear to have somehow participated in their own deaths. But when a brash rookie detective (Leo Rossi) pairs up with a cynical veteran (Robert Loggia) to track down the killer, the cat-and-mouse game ends in a deadly fight to the finish.
