A young girl is raped and strangled by the psychotic Alex and his retarded friend Ricky. They then help a wealthy couple with their car, and end up inviting themselves to their party. The houseful of bored socialites is looking for kicks, but they have no idea that there are two madmen in their midst. When the tension is broken, the party descends into an unrelenting series of rapes, mutilations, and murder.
Starring David A. Hess and Giovanni Lombardo Radice, and directed by Ruggero Deodato of Cannibal Holocaust fame.
