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.

After the argument with Johanna Augustin, Maria decides to write a book herself - easier said than done. And then her former best friend Nikki gets in touch. Maria avoids her problems and invites herself to go bowling with Sophie and her friends. Ralf spends the evening with his daughters, Lily and Lotta, trying to save what's left of his family.

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 wants to become a new man. Nikki forces Maria to have a day of reconciliation. They all end up at the "Holistic Healing Hatzfeld" wellness center at the same time: While Ralf and his friend Jochen face a dramatic firewalk there, Maria tries to avoid a serious conversation with Nikki. Will Maria and Ralf finally meet here?

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.
