The relationship of the Dutch Roman and the German Hanna - who live together in Berlin - is deadlocked. Will their relationship survive Christmas?

A supermarket is robbed. Commissioner Karl Jäger, who happens to be present, shoots the robber and is subsequently suspended from duty because the attacker’s weapon is not found. The incident also plunges Jäger into deep psychological problems. As a result, commissioners Lola Kraft and Jasmin Stein are called in when two bodies are discovered during the night of a class reunion at the Calw Hermann Hesse High School. All 29 party guests are considered suspects. When the investigators find out that their suspended colleague was a former classmate, his memories help advance the solution to the case, which has its origins in their school days.

Sonia breaks the perhaps most exciting time of her life, because the 20-year-old moves to Berlin for a mathematics study. Once there, she soon began to build up a new circle of friends, and then she fell in love with the kind, but irresponsible Ladja. There is only one big catch: the dear money is a bit scarce and therefore Sonia one day, financially, but also from curiosity, the path to prostitution. From now on, it leads a brisk double flight, which can fly at any time. Her experiences are ambivalent, as part-time she often gets into difficult situations, but also gets to know nice people, while she enjoys life just as a student. But how long can it maintain the double game?
