The Zombie Dead are unleashed when a professor's thirst for knowledge seals his own demise when he unwittingly unseals a cursed underground crypt in an ancient burial ground. The desecrated graveyard errupts with a ground swell of ravenous. rotting. flesh hungry zombies that shamble into the night in search of living human prey. On the adjoining grounds. a group of clueless. decadent socialites are enjoying a wild weekend retreat of debauchery. Among the eccentric guests are a nympho mother and her freakish. incestuous son. Unfortunately for the guests. their isolated country villa lies directly in the path of the flesh eating horde that have party plans all of their own!
