Schoolboy Jerôme Höffner, a brilliant nerd, is despised and pestered by his cool classmates, except assertive immigrant Said, who protects him. Foppish mother Debbie Höffners cool latest lover Marco Schmitz teaches his stepson to fight back against bullies, but breaking Jans nose in self-defense, Jerôme is forced in therapy with a child psychologist, who finds him a genius and recommends a mensa boarding school, but he willfully scores average on tests, fearing Debbie cant cope alone, until her clumsy attempts to offer enrichment privately frustrate him enough to visit, with Said, Dr. Kleybolds IQ school, which proves most tempting.
