Well-acted, wild, cross-genre mix of sci-fi and horror starring William Devane as a writer who takes a personal interest in a series of baffling decapitation murders in L.A., all of which seem to indicate some kind of supernatural force at work. Every night "The Mangler" stalks the streets, killing and mutilating one random victim. Also on the murder trail is a TV reporter (Cathy Lee Crosby), and a police detective (Richard Jaeckel), but despite their efforts only a mysterious psychic DeRenzy (Jacquelyn Hyde) knows what the killer really is and how to stop it.
A series of bizarre and seemingly random murders in Los Angeles are the cause for a widespread investigation. Detectives turn to a psychic for help.
