11-year-old Christophe tries to live up to his rigid and distant father on the family farm in rural France. But the young boy starts to lean over and collapse without warning — on the tractor, at school, at dinner... A doctor finds the solution: Christophe must wear an iron corset to keep himself upright. Forced to reinvent his life away from the farm, Christophe discovers a new passion for music, meets a new friend, and follows her into his first mischief.
