With France's 1981 presidential elections in the background, ordinary middle-class youngster Primo prepares to write the baccalaureate that he has already failed once. He gets side-tracked when he falls in love with a rich girl named Gabrielle. She hangs with a haughty, self-confident group of preppy youngsters who drive fast cars and vacation in Saint-Tropez. Their unlikely romance plays out against the bohemian lifestyle of our self-styled hero, who pretends to be something he is not to impress his new girlfriend. However, Primo is forced to bite his tongue as Gabrielle's friends casually air their right-wing views. As the election heats up, Primo finds it harder and harder to keep his thoughts and feelings to himself.
