Willi Zubrodt is delegated by his department to a parachuting course at the GST. As he is not very disciplined, has no respect for the instructors and does not fit into the collective, the instructors try to show him up and force his expulsion from the course. However, the attempts to prove that he had gaps in his theory and physical condition were a complete failure. Zubrodt manages to turn the tables each time.
