The bachelors Ernst Westerkamp and Kurt Felsing, an architect, are close friends, but there is a big difference between the two: While Westerkamp is very wealthy and lives in a beautiful house, Felsing is always short of money and currently even unemployed. Westerkamp has an expensive girlfriend in the dancer Marion, while Felsing has so far only kept one eye on Käte, the daughter of his landlady.
