From the twisted mind of Riccardo Freda, first maestro of Italian Gothic horror...

Ducking out of a summer storm, four hippies (led by Camille Keaton, star of I Spit on Your Grave) take refuge in the seemingly abandoned Villa Alexander...unaware that their hosts (Twitch of the Death Nerve's Luigi Pistilli and Thunderball's Luciana Paluzzi) are staging a satanic sacrifice.

When the ceremony ends in a bloodsoaked orgy of violence, the hippies flee the villa...only to find themselves accused of committing a Manson-style massacre.
