Three story-lines run in parallel in a town in Ile de France. Louis, a divorced café proprietor, flirts with every woman he bumps into, but doesn't develop any deeper relationship with them, except a growing affection for Sabine, the prostitute he sees regularly at a local hotel. His sister Agnès is a teacher, and is apparently happily married to Jean-Philippe, but he works very hard and doesn't seem to have been giving her all the affection she needs recently. She bumps into Stéphane, a young man recently returned to the town whom she knew as a child. He is obsessively interested in a young family who live nearby. The film gradually explores the hidden feelings and desires of each of the main characters. Will any of them find happiness?

Une petite ville... Père divorcé, patron de café, Louis éprouve pour Sabine plus que de l'affection. Ils se retrouvent souvent à l'hôtel, l'après-midi. Mais pour cela, il la paye. Elle a d'ailleurs d'autres clients... Secret, il ne confie sa peine à personne, même pas à sa soeur Agnès dont il est pourtant très proche. Celle-ci, institutrice, est mariée avec Jean-Philippe depuis longtemps. L'amour, la complicité et les années n'empêchent pas les mélancolies passagères. Un jour, Agnès croise Stéphane, un jeune homme qu'elle a connu enfant. Lui aussi transporte un lourd secret...
