Nothing original or innovative will be found in this slasher flick. The terror begins when a gaggle of coeds decide to celebrate their graduation in a secluded cabin in the woods. The owner of the cabin is an uncle of one of the girls. He was formerly an archaeologist, but one day, while excavating a site in a local cave he finds a big stone head that turns the uncle into a blood-thirsty beast. Back at the cabin, the party begins as the girls and their various guys engage in various erotic activities until the stoned creature comes along and brutally begins murdering them. The blood really starts flowing when a fugitive convict stumbles into the fray.
