Tommy Weidner (David Schütter) brings Ulla Wolf (Elisa Schlott) back from her admission interview at the University of Tübingen medical school to Dusseldorf on his motorcycle. It's a distance of roughly 300 miles. During the trip, Weidner smokes a cigarette. Even as the ash on Weidner's smoldering cigarette lengthens, the wind from the motorcycle ride miraculously doesn't blow the ash away.
Ulla does not seem to be a diligent medical student.
