A group of sixties teenagers bored with the party they’re at drive out to a deserted old mansion, but their laughter turns to fear when one of them is killed in a frenzied knife attack. Another of them persuades the rest that they should solve the murder themselves rather than go to the police, not surprisingly opening the way to further carnage.
