In this Christmas comedy, Academy Award-winning actor Christoph Waltz plays a pet shop owner who generally prefers animals to people. Recently divorced, he is still very attached to his ex-wife – who lives right across the hall from him.
Marion and Johannes share a bottle of wine together, and Marion admits that she has feelings for him and sometimes wishes they had never split up. But their moment is interrupted when Sascha appears and has a terrible accident.
All is lost for Johannes: He's unable to convince Marion that he didn't walk out on her, and even Sascha won't speak to him anymore. Johannes takes it upon himself to find the boy's father.
Johannes and Konstantin try to find Sascha's father. Then Sascha's mother comes to visit Johannes to compare notes – and accidentally rings Marion's bell.
