A group of friends play volleyball on a beach in Venice, California. Jackie, one of the group, is a high school senior throwing a slumber party that night, as her parents are out of town looking for a new house. When the friends leave the beach, one of the girls, Sarah, gets into her car and is brutally murdered by an assailant with a power drill. Jackie returns to her home, and finds her odd neighbor, Morgan, there, wanting to tour the inside of the house; he tells Jackie he is considering purchasing the property when she and her family move.

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 by an unseen assailant in the bathtub. Soon after, Maria finds Juliette's corpse in a closet. As Ken and Tom run to find help, they stop by a lumberyard to get weapons. Ken, revealing himself as the killer, proceeds to whack Tom with a sledgehammer, before slicing into his legs with a chainsaw. Ken goes to a van parked on the street where he has kept the bodies and a giant power drill. Inside, he examines a newspaper clipping regarding his police officer uncle Billy, and recalls how he was sexually abused by him, a trauma that has driven him to kill. 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.

Susie hides in an upstairs closet, but Ken attacks her and knocks her unconscious. Ken chases Jackie, Maria, and Diane into the basement, where they attempt to escape through a window, but he corners them. Jackie uses a spear gun to shoot him, and the three run back upstairs. Susie regains consciousness, and confronts Ken in the kitchen, blinding him by throwing bleach in his face. He continues to wield the drill, grazing Maria, who collapses. She offers herself to Ken sexually, but he grows enraged and impales her with the drill. Jackie and Susie manage to wrangle the drill out of his hands, while Diane clubs him in the head with a croquet mallet, knocking him unconscious. As the three contemplate what to do, Ken awakens and begins slashing Diane with a knife, killing her. Susie manages to pin Ken to the floor before Jackie viciously plunges the drill through his chest multiple times. After he dies, Jackie finds a folded photo in Ken's shirt pocket showing a childhood photo of him kissing his uncle on the cheek.

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."[5]
