Morning traffic on a freeway turns into chaos as a figure in a black winter coat throws a heavy metal rod from a construction site onto a car, killing the drive, merchant Stefan Krumm from Lüneburg, a fence inspected of counterfeit goods dealing. The conflicting witness descriptions seem to point to high-school maverick Marco Stieglitz, a bright, gaming-addicted loner into metal music. The team also finds serious conflicts among classmates.
