Jeanne has just found out that her school has been voted one of the top ten worst educational institutions in the country when the principal of the same school orders her to stand for election as student representative. To do penance for her vandalism of an advertising poster. At the end of the "Week of the Future" that the principal has just proclaimed, she has to give a speech against her competitors. Admittedly, the competition is not great: Olivier, who would rather save the whole planet than just the problem school, and Mike, whose slogan "Pizza for everyone" turns out to be the perfect populist election advertisement. Faced with the seductiveness of their classmates and confronted with the lack of advice and direction from the adults from whom they had hoped for support, Jeanne and Olivier discover the power of friendship and solidarity.
