The prisoner Klara Wendel was supposed to be deported from west to east Switzerland. But strange incidents occur during her transport, and all her companions disappear. Klara is found wearing a nun’s habit. To get to the heart of the matter, a tribunal is hastily set up in a barn. The judges want to find out how Klara has managed to escape and why she’s dressed as a nun. On trial by men, Klara somehow manages to take over and become the director of both the trial and the film.
