From the present-day metro, the camera takes us up to the surface, where we recognise a feverishly throbbing Berlin, 1931. This is the modern Grossstadt par excellence, captured at a highly complex moment leading up to a tragic future − we can see the Nazis already shouting in the streets. Our protagonist is the young Dr. Fabian, who works at an advertising agency during the day. In the evenings he explores the city’s extravagant nightlife together with his wealthy left-radical friend Labude, and he falls in love with the beautiful Cornelia. Political uncertainty and dismissal from his job don’t matter so much, but how can he reconcile his ironic detachment with the pain of love?
