Paranoia

“Orgasmo sucks you into a whirlpool of erotic love!”

Kathryn West (Carroll Baker), an American widow, moves to Italy after her husband's death and shuts herself away in a luxurious villa. Peter Donovan (Lou Castel), a local man, wins her over quickly, and she lets him move in, then his sister Eva (Colette Descombes) joins them. Umberto Lenzi fills the villa with wealth and sunlit excess, and the closer these two get, the less safe the place feels.
