Robert is a charming, middle-aged man, who is torn by the evident joys of freedom and of commitment to a relationship. One day, he is taken by his sister to visit a friend of hers who has just given birth. Surprisingly, Robert already knows the woman: she is Claire, an ex-girlfriend of his. Robert finds his feelings for her are returning, but, at almost exactly the same time, he meets a beautiful young model. They talk, he is intrigued, and they begin to see more of each other. Her name is Marie-Pierre, but everyone calls her Aie, the French word for "ouch". At first, Robert and Aie look like a deeply mismatched couple, but soon, Robert falls head-over-heels in love with her. Then again there is Claire, whose understanding and restraint is the perfect counterpoint to the rather mysterious and unpredictable Aie. Caught between two women, which one will Robert choose?
