The shy, well-employed Benoît's life changes when he answers the personal ad of Marie, a 25-year-old who restores paintings. He's attracted to her and she likes his steady calm and his honest attention. They're soon a couple, and they include Pierre in their dinners, outings, and trips. What will happen when Pierre realizes that he too is in love with Marie?
