A masked killer stalks an institution for mentally disturbed rich women.
Fernando Di Leo's 1971 thriller mixes horror and mystery as a masked killer prowls a secluded institution housing wealthy, emotionally troubled women. Leaning into the stylish, suspense-heavy traditions of European genre cinema, it trades on paranoia, hidden motives, and the question of who will survive the night. The mood is lurid and tense, built around isolation and dread rather than reassurance. With a MagicMovieScore of 4.8, it is aimed chiefly at genre enthusiasts and fans of vintage continental thrillers who appreciate atmosphere and mystery over polish, and prefer their suspense with a darkly retro edge.
