Psycho Cop 2

Psycho Copalso known as Psycho Cop Returns is a 1993 horror comedy film directed by Adam Rifkin, and written Dan Povenmire. It is the sequel to the 1989 film Psycho Cop.

Vickers sabotages the lifts, and when Mike goes downstairs to tell the night watchman about it, Vickers throws him down an elevator shaft. Vickers proceeds to send vaguely threatening faxes to the partiers, though this does not deter the drunken Gary from going up onto the roof with one of the strippers. The two are found by Vickers, who shoots Gary in the head, and throws the stripper off of the building. Vickers continues to send faxes, prompting Brian, Larry, and the remaining two strippers to go to the copy room, while elsewhere Vickers uses a decorative spear to impale a pair of workers who were having sex in a storage closet.Larry, Brian, and the strippers flee when Mike and Garys bodies fall through the ceiling of the copy room, and run into Sharon, an accountant who had stayed late. The quintet try to call 911, but the lines are not working, and while looking around to see if anyone else is in the building, they find the skewered couple, and are confronted by Vickers. Initially feigning being there to help, Vickers shoots Larry in the mouth, wounds Brian, and chases the others. The women try to escape through the front entrance, but the door is shatter proof, and handcuffed shut. While the trio make their way up to the garage exit, they are attacked by Vickers, who shoots one stripper, and snaps the neck of the other. Sharon is pursued by Vickers, but manages to set his face on fire causing one of his sunglasses lenses to melt to his eye and knock him down an elevator shaft, but he survives the fall. ........
