London, 1949. John Reginald Halliday Christie (Sir Richard Attenborough) is an unassuming, middle-aged man who, along with his wife Ethel, lives in the ground-floor flat at 10 Rillington Place. His demeanor masks the fact of being a serial killer. His modus operandi is to act as a person with a medical background, lure unsuspecting women to his apartment on the pretense of curing them of some ailment, knock them unconscious with carbon monoxide gas, gain his sexual release through contact with the unconscious body, then strangle the victim dead before disposing of the body somewhere in the house or outside area. His next intended target is Beryl Evans, a young woman who has just moved into the top flat in the house. Beryl's husband, Tim Evans, is an illiterate man who likes to put on airs. Already with an infant daughter named Geraldine, the Evanses learn they are going to have another baby, which they cannot afford to have, nor can they afford to abort the pregnancy. Based on a series of real-life killings, the story follows John Christie as he cons a pregnant bride (Judy Geeson) and wonders if he might have found a scapegoat in her husband (Sir John Hurt).—Neville C.
