Willi Kritz earns his living as a night watchman and corpse washer at the East German Pathological Institute at the Berlin Clinic. In the process, he found another source of income: he steals pathological exhibits and smuggles them to West Berlin disguised as a Berlin bear. His customer is Frundsberg, and the delivery always takes place in his Yankee sleigh.
