The Slumber Party Murders

So you thought it was going to be just another BORING weekend?... A group of pretty girls get ready for a party. Then an escapee from a local mental institution decides that he'd like to do a little partying himself. They've got potato chips, Coke & dope. They also get the odd severed head, bloody handprints -and a killer with a very novel style all his own. Even the poor pizza delivery boy ends up resembling his product. Its going to be no ordinary weekend. Pity they didn't stay at home.
