Marie-Hélène lives in a manor but is not happy. Georges, her husband, is gentle to her but she feels stifled by the constant presence of Cécile, her intrusive mother-in-law. One day, Jacques, a friend of George's comes to visit him. He is in the company of a beautiful woman, Françoise. Marie-Hélène, who feels ill-at-ease in her new environment, gets more and more attracted to Françoise. To such an extent that the two women fall in love. The lovers run away to the city but their affair will prove short-lived.—Guy Bellinger
