In the small town of Louvun, Marie and Léon Besnard live quite comfortably. But on 25 October 1947 Léon passes away. Nobody, including the doctor who issued the burial permit, is doubtful that his death was natural. Nobody except Louise Paniou, a friend of the couple's, who is persuaded that Marie has poisoned her husband.
