Joseph Galloudec seven years, lives in the eighteenth floor of a building in the Paris suburbs, between his mother Julia and her father Jean-Claude, a computer engineer and communist militant. His parents experiencing marital problems and his mother soon to give birth, he left for the summer holidays with his grandparents and three uncles, turbulent triplets. He discovers the castles of the Loire, Brittany and England. Upon his return, he met his sister Elisa, but her parents and tear her mother eventually left the home.

An epidemic of appliance madness unrelated to discount sales strikes an island off the coast of France: the islanders are being murderously attacked by ovens and refrigerators acquired in the same department store. Enter the young Dr. Gabrielle Martin (Anny Duperey), who arrives here to escape her own personal tragedy and instead lands in the middle of the kitchen mania. She tracks down the cause of the rapidly spreading epidemic to another doctor on the island — quite as insane as any of the kitchen appliances (if the comparison could be made) — and finds that the villainous doctor and the appliances have a most unusual link. Graphic scenes of mutilation by an oven, as one example, leave nothing much to the imagination in this film, but the interpretations of actors Anny Duperey and Jean-Claude Brialy as the good and evil doctors are excellent.
