After he calls 911 to report his wife’s accident, successful novelist and aspiring politician Michael Peterson becomes the prime suspect in her alleged murder.

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.
