Leben zu zweit

Karin, who is in her mid-thirties, works as registrar but has been divorced for several years. Together with her 16-year old daughter Nora, she leads a happy and independent life. Then, she finds a new partner in the mathematician Peter, but does not tell her daughter about him. When Peter proposes marriage, Karin always comes up with new excuses why such a step is still too early for her. She mainly fears that Nora would not be able to cope with another marriage of her mother. But when Peter cannot be dissuaded anymore by her excuses and finally wants to marry her, Karin comes up with a bizarre plan.
