Miriam Schenk and Paul Wolf and their almost grown children Zoé and Benno were a well-functioning patchwork family for years. The fact that there are cracks only becomes apparent when Benno's best friend Christopher is killed and the detectives Franziska Tobler and Friedemann Berg also investigate the Schenk-Wolf family's environment. Chris, they find out, was involved in the Freiburg drug scene and it seems obvious that his death had something to do with that. What did his close friend Benno know about it? After all, the two of them wanted to raise money for a trip around the world. And Zoé was also out and about with the two of them more than her parents ever noticed. Miriam and Paul's trust in their children and in each other is crumbling, while Tobler and Berg gather more and more evidence that their step-siblings are involved in dubious and increasingly dangerous financial transactions.
