Courtney Bates, who survived "The Slumber Party Massacre" as an adolescent, is now a senior in high school who is plagued by night terrors stemming from the event. In her nightmares, she is recurrently confronted by the killer, now reincarnated as a Greaser armed with a guitar fashioned with a massive drill bit on the Neck. At school, Courtney takes a liking to her classmate, Matt, and invites him to spend her birthday weekend with her and her friends, Amy, Sheila, and Sally. They plan to stay at a condominium in an undeveloped complex outside town where the girls, who have their own band, can practice music.
