Franziska only wants the best for her bright grandson Tobias. That's why the retired teacher is very worried when the boy starts to drop off at school. His mother Silke, a hands-on woman from a modest background, is not worried. She doesn't want to raise Tobias to be a bookworm anyway, but is annoyed that her dedicated grandmother spoils the little boy rotten. The fronts harden. After an ugly argument, Silke forbids her grandmother to have any contact with Tobias. Franziska doesn't want to put up with this and goes to court.
