In seinem Viertel in Berlin ist der junge Oberwachtmeister Schwenke überaus beliebt und immer gern gesehen. Zu jedem ist er charmant, freundlich und hilfsbereit, was den Polizisten zum Schwarm so manchen Mädchens macht. Dies gilt besonders für das Blumenmädchen Maria, Schwenke aber hat ein Auge auf die schüchterne Erna Zuwade geworfen. Doch Erna ist in dunkle Machenschaften verwickelt. Der betrügerische Karl Franke benutzt sie, um den Bankier Wenkstern und dessen Devisenschiebereien auszuspionieren, damit er ihn erpressen kann. Schwenke kommt dem Bankier zwar auf die Spur, doch von der Erpressung und der Beteiligung Ernas ahnt er noch nichts.

Oberwachtmeister Schwenke is universally loved in his district. Mary, the flower girl, especially has an eye on him. Schwenke is in love, however, with Erna, who is employed as a maid for the banker, Wenkstern. Wenkstern is being blackmailed by the crook Karl Franke, who, in turn, is receiving confidential information from Erna about Wenkstern's business affairs. When the police catch onto his dirty dealings and conduct a search of his home, Wenkstern flees and commits suicide. Erna, Franke's accomplice, but who was in love with Schwenke, is found murdered on the banks of the Spree near the Reichstag. The search is now on for Franke, who is found by Wenkstern's former driver, who breaks a few of Franke's ribs in the ensuing struggle. Franke is arrested by Schwenke after a chase and he accuses Schwenke of breaking his ribs in the arrest attempt. Sergeant Schwenke is then suspended for abuse of power during the arrest.
