The life of a band of teenager in a suburb near Paris. But instead of showing what would be the "urban legend" of this kind of poor suburb (violence, rapes...), Abdelatif Kechiche shows us what's the daily life of those guys: not much to do, not much dreams. Still, some of them have fun rehearsing for a play. Among those "players", Lydia, long time friend of Krimo... And Krimo, a bit shy, finds himself in love with this joyful girl.
