An American college student in Rome and his sister in New York investigate a series of killings in both locations where their resident addresses are the domain of two covens of witches.
From memory: The plot is barely comprehensible, but seen as an intense, horrifying and mesmerizing dream, made with a keen eye for style, it is a quite fascinating work of art.
Halliwell (no star): "Absurdly overplotted and mainly incomprehensible shocker with some small pretensions to style."
Maltin**1/2: "Surreal, hypnotic shocker...is short on sense, but long on style."
