Larry Cohen writes and William Lustig directs this chiller about a psycho in a police uniform who's terrorizing New York City with a series of random slayings. Lt. McCrae (Tom Atkins) believes a real cop is behind the spree and fingers young Officer Jack Forrest (Bruce Campbell). When McCrae becomes the killer's next victim, Forrest and an undercover vice cop (Laurene Landon) strike out on their own to solve the case and clear Forrest's name.
