Hilary Thomas is attacked in her Los Angeles home by Bruno Frye, a mentally disturbed man haunted by the voice of his mother. The intruder eventually leaves. But when she reports the crime, detectives tell her he has an airtight alibi. Frye then returns the next day and attacks Hilary again. This time she calls the police, who explain Frye has been found dead.
Hilary is attacked a third time by a man who appears to be Frye, but the man escapes before the police can arrive. After some investigation, one of the detectives puts her in touch with Frye's psychologist, who lets her listen to one of his recorded therapy sessions. On the tape, Frye expresses his theories about identical twins and shares his obsession with women he believes possess the spirit of his dead mother, who abused him and swore she would return from the dead.
A direct-to-video version of Whispers was released in 1990, directed by Douglas Jackson and starring Victoria Tennant as Hilary.
