Tommy Fikejs and Ferda Říha, two perpetual students, are completely broke. They are up to their necks in debt, their landlady is kicking them out, and there is no hope of securing another loan. Tommy does have a wealthy uncle—an automotive tycoon—but the man refuses to be "touched" for money, whether by persuasion or coercion, despite Tommy bombarding him with pleading letters.

Postman Brabec is a welcome guest of the revue theatre for his sense of humor, and he brings his director Holt letters from female admirers every day. Holt's fans include Brabec's sister Anny. The girl would like to join the theatre, but for the time being works as a maid for the actress Velden. A new revue is being rehearsed, the name of the author is secret. Veldenová will return the role just before the premiere because she doesn't like it. The quick-witted Brabec introduces the director to his sister, who knows all the parts by heart.
