Mein Sohn, der Klugscheißer plot
Bus driver Debbie Höffner and her son Jêrome couldn't be more different: she loves movies of cats and deep-cut cleavage, he loves his woolen hat and mental arithmetic. Because Jêrome is so different, his fellow students don't like him and he is bullied. He's resigned himself to that by now, something that Debbie's new friend Marco can't reach. When he takes that advice to heart and accidentally breaks someone's nose, he has to see a child psychologist. He discovers that he is gifted and it would be better to go to boarding school, where his abilities would be more effective. However, Debbie doesn't want to know about that...
