When she discovers her husband has come home with a mistress, Anne (Joanna Shimkus) leaves her home in Paris and spends the night in her office where she meets Francois (Michel Piccoli), an architect who, without asking any questions, invites her on a trip to the South of France. The two make the trip but become lost in the mountains and are put up for the night by a kindly baker. A visit to a sculptor friend allows Anne to tell her troubles to someone who cares. Francois overhears the conversation but says nothing to her. When they arrive in the South, Anne spies her husband's car, but he is nowhere to be found. Francois and Anne end up at the architect's house where they make love, but in an ironic twist, their romantic liaison is shattered when the man's wife returns home, and Anne considers returning home to her unfaithful husband.
