Hélène and François have been a happy couple for twelve years. The ace. Madame discovers the beauties of psychoanalysis in the guise of the attractive lecturer David Kouglow. Soon convinced that the good health and fidelity of her husband hide horrible tragedies, she decides three of her friends to help her so that her husband cheats on her so that she can assume his ulterior desires. But François discovers the truth. He decides to organize a somewhat special evening where, after the marital reconciliation, the doctor will observe in them another complex: that of Philemon and Baucis, which still suggests some small family dramas in perspective.
