As her neighbor Rémi Courmont has told her off for making his ears bleed with Ravel's Bolero, a music piece she plays at full volume all the time, Anne-Marie decides to get even with him. She sets up a hoax with the complicity of her friend Catherine, who agrees to post as Remi's mistress to embarrass him. Just then, Niquette, Rémi's real lover, resurfaces.
