The stenographer Inge and her fiance Karl go on a joyride and commit a hit-and-run after running down a child in the road. The landlady of a dubious inn, who finds out about their flight, turns over Inge to an Argentinian pimp and lets Karl get arrested by the police. In the "Casino International" in Rio, Inge is housed in a chapel and , like all the other girls there, has to prostitute herself to guests on demand. Karl, who in the meantime has been released from jail, finds out Inge's whereabouts and helps her flee.
