Le Bonheur.

Though married to the good-natured, beautiful Thérèse, young husband and father François finds himself falling unquestioningly into an affair with an attractive postal worker. One of Agnès Varda's most provocative films, 'Le bonheur' examines, with a deceptively cheery palette and the spirited strains of Mozart, the ideas of fidelity and happiness in a modern, self-centered world.
