With only 12 percent of its pupils obtaining their baccalaureate, Jules Ferry High School is the worst school in France. The Inspector of Schools has already exhausted all the conventional means to raise standards at the school and he has no choice but to take the advice of his deputy. It is a case of having to fight fire with fire: the worst pupils must be taught by the worst teachers...
Magali plays in a brass band. Guillaume drives a small tourist train. Both spin a perfect love, they share modest dreams and their baby is about to come. But an unexpected news upsets their routine: a man appears and announces that he is Guillaume's estranged father and also reveals that Guillaume is his legitimate heir of a kingdom offshore of France and England. Guillaume and Magali start to dream of a life as monarchs, surrounded by faithful subjects in their castle, enjoying their wealth. But reality is often different to what you can imagine.
