Given the question: Build a movie plot around this: Why are the doctor at the hospital swapping heathy village children for university children? Because of the poor bloodlines and genetic mutations in the faculty's inbred offspring
The answer is:
Detective Superintendent (Commissaire Principal) Pierre Niemans (Jean Reno), an investigator well known in Paris, is sent to the small rural university town of Guernon in the French Alps to investigate a brutal murder. The victim's body is found bound in the fetal position and suspended high on a cliff face, his eyes removed and his hands cut off. Niemans learns that the victim was a professor and the University's librarian, Remy Callois, and he seeks out a local ophthalmologist for an explanation to the removal of the eyes. Dr. Cherneze, once on the University staff, explains that the school's isolation led to in-breeding amongst the professors, with increasingly serious genetic disorders. Recently the trend has reversed, with the local village children becoming ill and the college babies remaining healthy. Cherneze hints that the killer is leaving Niemans clues to their motive by removing the body parts that are unique to each individual - the eyes and hands. Niemans questions the Dean and examines the librarian's apartment, where he finds images of athletic "supermen" juxtaposed with texts on genetic deformities. The Dean's assistant (and son) Hubert translates the title of Callois' Ph.D. thesis as, "We are the masters. We are the slaves. We are everywhere. We are nowhere. We control the crimson rivers."Coincidentally Detective Inspector (Lieutenant de Police) Max Kerkerian (Vincent Cassel) is in the nearby town of Sarzac investigating the desecration of the grave of Judith Herault, a girl who died in 1982, and the theft of her photos from the local primary school. The girl was killed in a horrific highway accident, witnessed by her mother, who was so traumatized she took a vow of darkness in a nunnery. The mother tells Kerkerian that when Judith was ten she fell ill, and they went to get help in Guernon where she was born; she claims they were then attacked by "demons" and, when they fled, her daughter was killed in the road accident. She says the pictures were stolen to erase her daughter from history,...
