After a young woman and her grandfather run into financial trouble, she (forced by a thief to wear his clothes) tries to earn money selling newspapers, loudly yelling false news to advertise them.
A young doctor arguing that "truth is the mothermilk of the civilisation", destroys the newspapers and tries to leave in his car, but is blocked by her, causing him to destroy a telephone booth.
Arrested still wearing the thief's male clothes with his wig found in the trouser pocket, she and grandfather are dragged in front of an understanding but severe judge who make them to pay for the telephone booth.
The doctor, moved by the tears for having caused trouble for the 'boy' and her grandfather, asks his garage manager to hire 'him' and secretly pays the fine.
When she discovers the doctor has no clients, she starts helping him find some in daring ways. The doctor discovers she is not a boy, but continues the charade. There is a happy ending when she finds out he has secretly helped her and her grandfather.
Production
The film was made by German-based subsidiary of the American studios Universal Pictures, whom Gaal was under contract to. The rise of the Nazi Party mean that Gaal could no longer work in Germany, so production of her films were switched to Vienna and Budapest.
