After his divorce, sports store owner Ralf is looking for a new purpose in life - and a new love. But is there anyone in Marburg he doesn't know? Bookseller Maria encounters an old rival - both her affair Max, and her father are just waiting for her to lose her temper. Things escalate - and lead to a surprising encounter.

Maria tries to come to terms with an unpleasant truth about Max. Her father also surprises her with an unexpected confession. Even the unwanted psychological advice from dog trainer Hakan doesn't help. And Ralf also has to deal with some bad news that changes his entire life - he gathers the whole family together for a big dinner...

Ralf is on the lookout: who is the mysterious woman who always writes on his car? After a misunderstanding, he suddenly has a dog and a date with a stranger that takes a completely unexpected turn. Maria also has a date - and gets carried away with an act that ends the day in disaster.

Max and Nikki's wedding is on the rocks, but Maria wants to save it - and finally draw a line under it and concentrate on her career as an author. Ralf has to take care of Schopenhauer's funeral - until he realizes that he has to stop the wedding.

After the scandal at the wedding, Maria flees to Cologne to talk to the publisher about her book idea. After a promising start, however, the conversation goes completely off the rails. Just a few streets away, Ralf says goodbye to his daughter Lily as she embarks on her future life as a student. A fateful coincidence?
