Plot
A group of friends are playing volleyball at a Los Angeles beach. Jackie is a high school senior throwing a slumber party that night. When they leave the beach, one of the girls, Sarah, gets into her car and is brutally drilled from behind the seat. That night, Jackie's friends, Diane, Maria, Juliette, Janine, and Susie, arrive for the party. Shortly after, three boys, Frank, Tom and Michael, arrive and scare them. Jackie angrily tells the guys to leave. Frank and Tom go get something for the girls while Michael goes to apologize to them. Michael encounters a masked killer, who impales him with a "house for sale" sign post. After another boy, Duncan, bribes a pizza delivery girl into delivering the pizzas to the girls, she is chased and murdered by the same killer. The girls let Frank and Tom in the house, and Ken, Juliette's love interest, appears right behind them.

Upstairs, after Juliette and Ken have sex, Ken leaves and Juliette is electrocuted in the bathtub. Soon, Maria finds Juliette dead in a closet. As Ken and Tom run to find help, they stop by a lumberyard to get more weapons. Ken whacks Tom with a sledgehammer, before slicing into his legs with a chainsaw. Ken goes to a van where the dead bodies, and the drill are. Ken is revealed to be the killer. Back at the house, Ken barges in and kills both Duncan and Frank. Janine and Maria run to the door but Ken follows and Maria flees. Janine jumps through the glass door and Ken drills her in the back, killing her. Jackie shoots Ken with a spear gun and Susie throws bleach into his face, blinding him. However, Maria collapses after Ken grazes her with the drill and he kills her aswell. Jackie and Susie knock the drill away from him, while Diane whacks him until he is unconscious. Ken soon awakens and repeatedly stabs Diane with a knife, killing her. As Susie holds him down, Jackie viciously drills Ken to death, finally killing him. Jackie and Susie leave the scene.

Reception
In a contemporary review, Variety noted that the film "eschews the role-reversal aspects of Amy Jones' superior 1982 original". The review noted the film was poorly scripted, the "gore is plentiful but unimaginative", and that "by the final reel, when five full-bodied females are scurrying helplessly as the man wielding the phallic drill skewers them, even die-hard genre fans will be groaning in dismay."
