In 1916, beautiful young mute Helen is a domestic worker for elderly, ailing Mrs. Warren. Mrs. Warren's two adult sons, Albert (a professor) and womanizing impudent Steven, also live in the Warren mansion. Mrs. Warren becomes concerned for Helen's safety when a rash of murders involving 'women with afflictions' hits the neighborhood. She implores her physician, Dr. Parry, to take Helen away for her own safety. When another murder occurs inside the Warren mansion, it becomes obvious that Helen is in danger. 哑女惊魂记。The Spiral Staircase。竟是卧床不起的老太救了海伦。转载老片网的信息。
