The teenagers Sven and Jonny have a dangerous hobby: they let themselves be pulled along the highway by trucks on rollerblades. Sven discovers that a truck is loaded with heavy weapons. As he flees, he is seen by the corrupt police officer Peter Mentner. Sven now knows about a planned arms deal. Semir and Tom take on the case and come across the rollerbladers, without knowing that this case is connected to a larger arms deal.
