Keinohrhasen (2007)

Gossip-columnist Ludo finds himself sentenced to three-hundred hours of community service after he literally crashes a private celebrity party. The work is at a children's day-centre and while the job's fine it is his bad luck that the person in charge is a woman whom he used to play endless practical jokes on when they were at school; she hasn't forgotten and is prepared to use her new-found power to get her own back. She finds however that, like the children, she's warming to him. If only the court injunction had stopped his womanising too.
