In Bremerhaven, one of the largest automobile transshipment ports in Europe, a body is found at one of the car terminals - the driver area manager is lying dead in the trunk of a car. The Bremen investigative team with Liv Moormann and Linda Selb begins the investigation and is supported by their Bremerhaven colleague Robert Petersen. They come across Marie, Gheorghe Rusu and Oleg Rusu. The three car tuners secretly send cars along for night races and compete in spinning "doughnuts" when the car slides in circles with smoking tires. One of the vehicles turns out to be particularly explosive. Liv Moormann quickly finds herself in the middle of the car tuning scene - and as a native of Bremerhaven, she not only meets forgotten friends, but is also confronted with her own family.
