Black Sabbath

“A story that goes beyond the boundaries of the Supernatural to the half-world of the living dead...Where a woman's soul inhabits a fly's body...Where vampires suck only the blood of those they love dearest.”

A woman alone in her apartment keeps answering a phone that brings a voice she cannot place. That is Rosy (Michèle Mercier), the first of three stories Mario Bava gathers here, with Gorca (Boris Karloff) coming home to his family in the second and a dead medium in the third. Introduced by Karloff himself, the tales share one plain fear: that what threatens you is already inside the house.
