Der König von St. Pauli
Rudi, who operates a striptease club in St Pauli, incurs immense gambling debts. The situation gets worse when his rival Graf, a fishmonger, enters the scene.

The glamorous reopening of the "Blue Banana" is a huge success, but intrigue causes Rudi Kranzow to lose his license for the time being. He also threatens to lose Julia, because the new star stripper turns to her ex-lover in Munich in disappointment, as Rudi demonstratively ignores her for fear of becoming too attached. Rudi is and remains a gambler: when the "Count" offers to gamble for the Kranzow house, he cannot say no.
