Una gota de sangre para morir amando (English: Murder in a Blue World) is a 1973 Spanish/French film directed by Eloy de la Iglesia and starring Sue Lyon, Christopher Mitchum and Jean Sorel. Shot in English and set in the near future, the film is a crime thriller.

The plot follows a respectable nurse, who seduces young men, take them home to bed, listen to the post-coital beating of their hearts, and then stab them to death with a surgical scalpel. The film takes some cues from Stanley Kubrick's A Clockwork Orange to the extent of being released on UK VHS as Clockwork Terror.

Anna Vernia, a beautiful young nurse, receives a medal of recognition for her outstanding dedication to her patients at the medical center where she works. She is going out with Victor Sender, a doctor working in the same hospital. Victor is deeply involved in a project that employs electro-shock therapy in violent criminals in an effort to turn them into model citizens.

Crime is rampant in the city. There has been a number of unresolved killings of young men which have been attributed to a serial killer believed to be a sadistic homosexual. A family is getting ready to watch Stanley Kubrick's A Clockwork Orange on television when they are assaulted by a gang of delinquents who knock at their door. The assailants, wearing red helmets, leather biker’s outfits, and handling bull whips smash the modern looking apartment. They rape both husband and wife, but leave the couple’s young son unharmed. After their crime, there is a dispute among the four members of the gang. One gang member, David, is beaten up and expelled from the group.

Anna is a pop art collector. She is the highest bidder in an auction of Alex Raymond’s artwork for Flash Gordon. At the auction she gives her phone number to her bidder rival, Toni, a young man with a handicapped leg. Anna lives alone in a large mansion in the outskirts of the city where Toni comes to see her. After they have sex, Anna listens to Toni’s heart beats while he sleeps and stabs him to death with a surgical scalpel. She disposes Toni's body in a river, but she has been secretly observed by David. He finds out Anna's information through her car’s number plate and begins to follow her. Wearing a wig and dressed matronly, Anna seduces Bruno, a narcissistic underwear model, who she has seen on T.V commercials. She takes him home and kills him. His body falls next to the book Anna was reading: Vladimir Nabokov's novel "Lolita".
