Irma Caspari has dropped her studies and now tries to make a living as a cleaning woman.
Her new clients, the Schwarz family, seem to belong to the upper class. Frau Dr. Schwarz is a judge and will be elected state's supervising judge in the near future.
Irma has her own point of view about the rich. She has no problems using the Schwarz' luxurious bathtub while she should be working.
One day Irma discovers something strange. Obviously the Schwarz family has someone arrested in the cellar: an old woman is laying in the dark groaning.
Irma decides to do something about it.
