When the moon turns red, the dead shall rise.
The nights of terror are unleashed when a professor's thirst for knowledge seals his own demise as he unwittingly unseals a cursed underground crypt in an ancient burial ground. The desecrated graveyard erupts with a groundswell of ravenous, rotting, flesh-hungry zombies that stalk 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 has party plans of its own!
