Jane is tormented by her mother’s murder when she was a child, by a recent car crash that claimed her unborn child, and by terrifying nightmares of a blue-eyed knife-wielding killer. Her husband recommends vitamins, her sister recommends psychotherapy, and her neighbor recommends participation in a Black Mass.
The first half of the movie, in which Jane is stalked by a silent blue-eyed man who may or may not be a figment of her imagination, is better than the second half, after she starts to participate in a Satanic cult’s ritual orgies and plunges deeper into insanity. But it’s still a solidly tense and unsettling movie that shifts between dream and reality, keeping the viewer off balance and delightfully confused. Though the director and most of the actors worked in the giallo genre, this is far more gothic than giallo in tone, with its dreams, mysterious castle, and dark occult activities. The movie wraps up like a giallo, though, a little too neatly, with the dastardly plot exposed; it would have been a more satisfying film if things had been left a bit more mysterious and unexplained.
