Frightmare (1974 film)

Plot

Dorothy Yates lives with her husband Edmund in an isolated farmhouse in Surrey. They have just been released from a mental institution to which they were committed in 1957 after it was found Dorothy was a cannibal who killed and partially ate at least six people.

Jackie, Edmund's daughter by previous marriage, lives in London but secretly visits her dad and stepmum at night to bring her parcels containing animal brain, thereby implicitly feigning to commit murders for her so as to contain Dorothy's murderous urges. Now, it seems as if Dorothy has had a severe relapse. She secretly lures lonely young people to her home, promising tea and a tarot card reading, only with the sessions ending with a violent murder and "feast". At the same time, Jackie tries to control her 15-year-old half-sister Debbie, Dorothy's actual daughter that she and Edmund had shortly before being committed to the asylum. Debbie has been recently thrown out of the orphanage. She now stays with Jackie and rides with her boyfriend Alec, head of a violent biker gang. Debbie incites Alec to start a fight with a barman in one of London's hip nightclubs because he denied her liquor due to her being underage. When they get thrown out, the bike gang later ambush and assault the barman with a chain but leave when spotted. Debbie, however, decides to stay behind and hides the body in the trunk of a car before the police arrive. When Jackie berates Debbie for coming home late, they have a severe argument in which Debbie in turn asks where Jackie goes at night.

It is later revealed that her cannibalism can be understood as an attempt to cope with a childhood trauma when she found out that she had eaten parts of her pet rabbit that her parents had cooked and served as dinner. Although her husband Edmund was convicted, it is later revealed that he only faked his dementia in order to remain with his wife. He is a truly devoted husband who loves his wife dearly and does not take part in the actual acts of murder in 1957 and in the present, only helping in covering them up.

When Jackie discovers Debbie's bloodied jacket and finds out from her that she was involved in the barman's murder, she and her boyfriend Graham, an investigative psychiatrist who has in the meantime himself found out about Jackie's family history, lead the police to the body in the trunk, which is missing an eye - a wound that could not have been inflicted with a chain and is reminiscent of the wounds inflicted by Dorothy on her victims. As it is thus revealed, Debbie and Dorothy have been secretly meeting without Jackie's knowledge, and Debbie has apparently taken on her mum's pathological urges herself.

Meanwhile, Debbie escapes with Alec to the farmhouse, where Dorothy kills Alec. Jackie suggests that Graham call on her stepmum, and he goes there alone to talk to Dorothy, with Jackie following shortly after. When Graham arrives, Debbie reveals his identity to Dorothy, who kills him. When Jackie arrives, she encounters her dad alone, who tells her they feel Debbie belongs more to them than she. She starts looking for Graham and finds Dorothy and Debbie with his body in the attic. As Dorothy and Debbie circle in on her, Edmund, who has followed her there, blocks the door. As Jackie cries for his help, the film closes with a freeze frame of Edmund restraining his urges to come to her aid and looking in dismay at his daughter's imminent demise with a voice-over of what the judge had said to him and Dorothy when they were sentenced to the mental institution in court.
