Shivers, also known as The Parasite Murders and They Came from Within, and, for Canadian distribution in French, Frissons ( ; 'chills' or 'shivers'), is a 1975 Canadian science fiction body horror film written and directed by David Cronenberg and starring Paul Hampton, Lynn Lowry, and Barbara Steele. Plot At Starliner Towers, a luxury apartment complex outside of Montreal, Dr. Emil Hobbes murders a young woman named Annabelle. He slices open her stomach, pours acid into the wound and then commits suicide. Nick Tudor, who has been suffering from stomach convulsions, finds their bodies but leaves without calling the police. The two bodies are found by resident doctor Roger St. Luc, who calls the police. Hobbes' medical partner, Rollo Linsky, tells St. Luc that he and Hobbes had been working on a project to create "a parasite that can take over the function of a human organ".

Hobbes believed modern humans had become over-intellectual and estranged from their primal impulses. Hobbes' ambition with his parasitic invention was to reassert humanity's unbridled, sexually aggressive instincts, and he used Annabelle as his guinea pig. Linsky warns Roger not to approach anyone who is behaving in a strange manner. Nick tries to force Janine to have sex with him, but she recoils in horror when one of the parasites crawls from his mouth. She rushes to the apartment of her friend Betts, who was infected by one of the parasites while taking a bath. Betts seduces Janine and as they kiss, passes a parasite to her. Meanwhile, other residents, including a little girl in an elevator with her mother, who are assaulted by a
