Benoit’s first week at his new school does not go to plan. He’s roughed up by Charles’s gang, the popular kids, and the only pupils who welcome him with any kindness are the «nerds». Fortunately, there’s Johanna, a pretty Swedish girl who Benoit makes friends with and whom he falls for. However, little by little she drifts away to join Charles’ gang. On his uncle’s advice, Benoit organises a party and invites his entire class. It’s his chance to become popular and get Johanna back.
