We follow Nick G. and Lars K. through a fateful night. They are going to kill their friend Miriam K. Beyond their wish to see someone die, there is no motive. 39 knife stabs. That's all.

The dead woman is the controversial family court judge Sophie Nöll. Chief Inspector Moritz Herbst therefore doubts that it was an accident. Mala quickly recognizes signs of a crime. Those who were severely affected by Nöll's judgments are now suspects.
