Slaughter Hotel (), also known as Asylum Erotica and Cold Blooded Beast, is a 1971 Italian giallo horror film directed by Fernando Di Leo and starring Klaus Kinski. The film follows a masked killer murdering the wealthy female inmates of a sanitorium. The building that was used as the mental hospital in this film was used several years earlier as the set for the 1966 giallo The Murder Clinic. Plot A hooded, axe-wielding killer lurks around a large rural villa which has been converted into an asylum. It begins when a woman named Ruth is committed to the clinic by her husband. She attempts to escape by assaulting an orderly as well as attempting suicide, but is restrained. One of the residents, named Cheryl, is visited by her husband, Mr. Hume, who had committed her because of a suicide attempt due to her stressful job working as head of their company. Mr. Hume talks with the clinic director Dr. Francis Clay and his associate, Dr. Austin, about the possibility of Cheryl being cured. Dr. Clay tells Mr. Hume that Cheryl's suicidal urges may relapse once she is released, but Hume thinks that his wife only needs some more rest at the clinic. Meanwhile, Helen is a nurse who is tending to resident Mara, who tells Nurse Helen that she seems to be improving with her treatment. Another patient is Anne, who is a diagnosed nymphomaniac. Anne attempts to follow the gardener to seduce him, but she is called back to her room by Dr. Austin, who counsels her about her "impulsive" and "excessive" sexual desires. Anne is visited by her brother, Peter, and wants them to return to the 'affectionate' ways they together had as children, and clearly has sexual feelings for him. Peter says they must resist this now they are adults. Later that evening, as the attendants and patents sit in a room to mingle and play cards and board games, Anne sneaks out the front door and runs to the greenhouse. The hooded and cloaked person is outside, and after a nurse walks by (seeing and ignoring the person), she is beheaded with a scythe. Anne sees the gardener, takes off all her clothes, approaches him, and seduces him into having sex with her in the greenhouse. Meanwhile, Helen goes to Mara's room and tells her that she can join the others if she wants and says
