Italian horror icon Riccardo Freda directs I Spit on Your Grave star Camille Keaton in this gory shocker concerning four hippies who seek shelter from a summer storm in a seemingly-abandoned villa, only to realize that they have stumbled into a satanic sacrifice. Frightened away by the gruesome orgy of violence, the hippies waste no time in beating a hasty retreat. Things quickly go from bad to worse, however, when the innocent peaceniks are subsequently accused of committing a massacre that eclipses that of even the Tate-LaBianca murders.
