A macabre student prank ends fatally. After Karim, Pascal and Enno stuck a curly tail between the buttocks of their dead teacher Dirk Rebmann in the funeral home to show him their contempt posthumously, the totally drunk Enno falls asleep on a gurney. His buddies leave him behind, and the boy is dead the next morning. He froze to death in the cooling chamber. That calls chief inspector Jens Stellbrink (Devid Striesow) and his team into action. But what initially looked like a schoolboy prank with a fatal outcome is a bit more complicated at second glance. And when Stellbrink also discovered symptoms of poisoning on the corpse of the dead professional cyclist, even two deaths had to be clarified.
Stellbrink and his colleagues Lisa Marx (Elisabeth Brück) and Mia Emmrich (Sandra Maren Schneider) first investigate the dead boy's circle of friends and come across some problematic father-son constellations and a star chef who has a lot to hide.
