Tom Kranich's first day with the highway police starts off fast: he's late and crashes his bike into an old Benz. The driver, Susanne, is on her way to Aachen with her niece. Her passenger is businessman Ed. Susanne offers to drive Tom to the station. He accepts the offer, gets in the car and the drama begins: the accelerator has jammed, the car is speeding along. Semir learns via cell phone that his new colleague is in danger. They manage to clear the route. There is a risk that the car will fly off the road in a long bend. Tom risks his life when he tries to tear off the fuel line. The attempt goes wrong. Although they managed to avoid the dangerous bend, they are now racing towards an open drawbridge, which the district president claims is defective. Engelhardt does not believe that this is the truth, but her hands seem to be tied...
