At the centre of the story is Miss Lenka Stříbrná. An attractive, but a little strange young woman. The gym teacher Vasek is shy and very clumsy with women. So he asks his friend, the editor Karel, for help. The experienced seducer willingly seizes the opportunity and tries to win Lenka for himself, but all his efforts fail due to her stubbornness. Gradually, this comedy-tinged love etude gives way to drama. It culminates at an editorial party at the Slap Dam, where all the characters in the story meet unexpectedly and editor Leden finally understands what Miss Silver's flirtation was all about.
