The main characters are a young psychologist Doubravka and a village youth, Honza Macháček. He is a tractor driver who temporarily lost his driver's license in a crazy bet, so he now herds a cooperative herd of cows, she is at the cottage with her boy Boba, who is not very successful in studying medicine and is currently preparing for his remedial exams. Honza's immediacy, optimism and approach to life and work contrast sharply with the selfish, weak-willed and unbalanced Boba, and Doubravka increasingly realizes that her feelings for Boba have disappeared and that she actually loves Honza. The question is how her somewhat conservative family will view such a game.
