Faded Hollywood star Katharine Packard (Miriam Hopkins) lives a lonely, secluded life in a sprawling mansion, battling the bottle and struggling to hold on to her eroding sanity. After a drunken reverie leads to a broken leg, her doctor advertises for a live-in nurse to help care for the embittered former actress. An intense, sarcastic young man named Vic (John Garfield, Jr.) arrives to claim the assignment, and is hired despite the concerns of Ms. Packard's secretary (Gale Sondergaard). She's right to suspect the worst, for not only is Vic lying about his medical credentials, he's also a psychopathic killer who preys exclusively on older women. He charms his way into Katharine's good graces, seduces the comely young cook (Virginia Wing) and keeps a secret leather kit full of syringes, butcher knives and scalpels hidden in his room. Katharine thinks she's falling in love and soon Vic is in full control of the household, charging expensive outfits for himself and bringing drug dealers and freaks back for midnight parties. When the elderly screen legend realizes that her young gigolo is dangerous, she mysteriously disappears, but Vic tells the household staff that Katharine is simply isolating herself in her room and doesn't want to be disturbed by anyone but him. As the domestic help start to get wise, they are picked off one by one by this remorseless predator. Also known as The Comeback and Hollywood Horror House.
