In the face of two world wars, Professor Prätorius, a philanthropist and a surgeon, wants to exterminate the one danger to mankind, the microbe of stupidity, as he states in a spontaneous lecture to his male and female students. When he tries to help a pregnant girl he gets involved more and more in her life and is forced to marry her.
