Back in 1916, amazing young mute Helen is just actually a nationally worker for elderly, ailing Mrs. Warren. Mrs. Warren's two adult sons, Albert (a professor) and womanizing impudent Steven, also reside in the Warren mansion. Mrs. Warren becomes worried about Helen's safety when a rash of murders between'women with afflictions' strikes the neighborhood. She implores her doctor, Dr. Parry, to shoot Helen away for her own safety. It becomes obvious that Helen is at peril, when a second murder occurs in the Warren mansion.
