Frau Gelli runs a reform school for young women from wealthy families with social behavior issues. In order to educate them, Frau Gelli imposes a violent discipline, in which she is assisted by two bedels, Kranz and Hanz. Punishments against the students reach unbearable levels, and many try unsuccessfully to escape, until Solange, the most rebellious of the students, after being severely punished, plans a riot.
