Sept morts sur ordonnance (Seven Deaths by Prescription or Bestial Quartet) is a 1975 French drama film directed by Jacques Rouffio and starring Michel Piccoli, Gérard Depardieu, Jane Birkin, Marina Vlady, Charles Vanel and Valérie Mairesse.

Pierre Losseray is a surgeon at the public hospital in a small provincial town in France (Clermont-Ferrand).

He is appreciated by his patients, and is being harassed by Old Brézé, the owner of a nearby medical clinic, who is losing clients and cannot stand competition.

Berg had killed his three children, his wife and finally himself, apparently when under such pressure; however the real reason of why he did that remains unclear : he had much charisma, a Boston University diploma, an excellent reputation, a charming wife, and was even about to launch his own private clinic.

A major role is held by Mathy, a psychiatrist who happens to know, because of his social relations, all the clues about the former story, but gives them reluctantly because he wants to be in good terms with everybody.
