Psycho Cop is a 1989 American slasher film, released direct-to-video. It was written and directed by Wallace Potts, noted for its similarities to the previous year's Maniac Cop by William Lustig and Larry Cohen. It was followed by a 1993 sequel entitled Psycho Cop 2.
Two lost newlyweds named Barbra and Greg stumble onto the site of the ritualistic murder of a woman by Joe Vickers, a corrupt police officer and serial killer who is also a Devil worshiper. Vickers murders both of them. The next day, three couples travel to a secluded mansion that they have rented and are given a tour by the property's caretaker, who is later murdered by Vickers. Upon noticing the caretaker's disappearance, the couples go looking for him and encounter Vickers, who reassures them by claiming that the caretaker injured himself chopping wood and is now recovering in the hospital. That night, Zack leaves to get beer and is killed by Vickers via bully club being shoved down his throat.
Vickers proceeds to butcher Eric, Julie, and Sarah. Doug and Laura realize that Vickers is the culprit by his shoes prints and are chased into the forest where they are found by a pair of policemen, Chris and Bradley. Before being killed by Vickers, the officers reveal that he is really Gary Henley, a discharged psychiatric patient who has somehow infiltrated the California Police Department. Laura is pursued by Vickers to a clearing containing the crucified bodies of Zack, Julie, Eric, and Sarah. Laura shoots Vickers with his own sidearm, but he is unaffected. Vickers is finally defeated (and seemingly killed) when he has a sharp log thrown through him by Doug. Emergency services greet Laura and Doug at the mansion as Vickers recovers and a newscast announces that further evidence indicates that he is actually an escaped psychopathic serial killer named Ted Warnicky. The film ends with Vickers smiling evilly at the camera.
