Es werde Licht! 3. Teil (1918)

In the third part syphilis is also at the center of the action. This time a landowner falls ill. He proves to be a real fiend, tyrannizes his wife and seduces the daughter of the forester he employs. When the young woman thinks she can't find a way out, she seeks suicide. Finally, the despot also dies and, post mortem, takes his son with him into the misfortune. The latter believes that he too is suffering from syphilis and is soon obsessed with this delusion.
