Dr. Sommerfeld is torn between two attractive women: Both Dr. Irene Kürschner, with whom he works brilliantly in the shared practice at Bülowbogen despite occasional atmospheric disturbances, as well as the successful and elegant PR agent Nora Hansen covet the likeable doctor. While Sommerfeld keeps losing his rhythm during his hot dance at two weddings, his daughter Nina tells him that she finally wants to move out. On Nora's advice, Sommerfeld tries to lock Nina in a golden cage by renting an apartment directly opposite over her head. When Nina gets wind of the matter, she runs away. At first insulted, then horrified and increasingly frightened, Sommerfeld sets out to search - and is surprised to learn that he doesn't actually know his daughter. When he finally finds her again in Meißen after a real odyssey, Nina drops the real bombshell: she is pregnant, but stubbornly refuses to give the name of the child's father. Sommerfeld, as always a man of action, takes the two potential son-in-law aspirants seriously - of course again without Nina's knowledge. But then suddenly a third candidate, Irene's son Benjamin, comes into play completely unexpectedly. At some point it all becomes too much for Sommerfeld - luckily he still has his best friend Luca, with whom he quickly jumps onto the motorcycle and flees. But on the way, Luca has to make a very embarrassing confession to his friend.
