Dorothy Yates Sheila Keith and her husband Edmund Yates Rupert Davies reside in a remote Surrey farmhouse, recently released from a mental institution after it was revealed that Dorothy is a cannibal who killed and partially ate at least six people. The couple’s uneasy peace is shadowed by a complicated past and a fragile present, where appearances of safety mask darker cravings.
Jackie Yates Deborah Fairfax, Edmund’s daughter from a previous marriage, travels from London to visit at night, slipping parcels containing animal brains to her father and stepmother. It’s a deliberate ruse to feign murder for Dorothy’s sake, a way to steady Dorothy’s growing murderous urges while giving Jackie a sense of control over the family danger. Jackie’s secret nighttime routine becomes a uneasy ritual that threads through the household, hinting at the deeper layers of manipulation and fear.
Debbie Yates [Kim Butcher] is Dorothy’s 15-year-old daughter, recently removed from the orphanage. She stays with Jackie and becomes entwined in a reckless scheme with Alec Marini [Edward Kalinski], her boyfriend and the head of a violent biker gang. Debbie’s impulsive energy pushes them toward trouble: a reckless confrontation in a London nightclub with a barman who refuses to serve underage drinkers, followed by a violent ambush with a chain. Debbie, however, hides the body in the boot of a car before the police arrive, setting off a chain of consequences that ripple through the family.
Although Dorothy appears to be “cured,” a darker truth lurks: she secretly lures lonely young women to her home under the pretense of tea and a tarot-card reading, only to end the sessions with brutal murders and a ritual feast. This chilling cycle peels back the surface of harmless domestic life to reveal a predator feeding on vulnerability, with the threat staying just beneath the surface of the ordinary.
The film slowly uncovers the root of Dorothy’s cannibalism as a coping mechanism for a childhood trauma. She discovers that she once ate parts of her pet rabbit, a discovery that horrified her and shaped her later actions. Edmund’s role in the 1957 case is complex: he was convicted, but the truth emerges that he merely faked dementia to remain with Dorothy, a devoted husband who did not take part in the killings but helped cover them up.
When Jackie learns of Debbie’s bloodied jacket and Debbie’s confession about the barman’s murder, she and Graham Heller [Paul Greenwood], an investigative psychiatrist who has uncovered the family history, drive the police toward the body in the boot. The discovery that the body is missing an eye—an injury that could not have been caused by a chain—hints at Dorothy’s signature brutality and deepens the mystery surrounding Debbie’s involvement.
As the web tightens, Debbie and Dorothy have been secretly meeting without Jackie’s knowledge, and Debbie seems to have inherited her mother’s pathological urges. In a pivotal turn, Debbie flees with Alec to the farmhouse, where Dorothy overtly ends Alec’s life. Jackie calls Graham to confront Dorothy, who goes to the house alone to face Dorothy; Jackie follows soon after.
When Graham arrives, Debbie reveals his identity to Dorothy, who reacts with lethal resolve. Dorothy kills him, and when Jackie arrives, she finds Edmund alone, who tells her that they feel Debbie belongs more to them than to her. A tense search leads Jackie to discover Dorothy and Debbie with Graham’s body in the attic. Edmund, who has followed, blocks the door as Jackie pleads for help. The scene ends on a freezing image of Edmund restraining his own murderous urges, looking in dismay at his daughter’s imminent danger, while the judge’s doubt-filled words from the courtroom where they were sentenced to the asylum echo over the final moment.
