A beautiful girl Katya has found her happiness. Her chosen one Andrey is not a prince maybe, but a kind and decent guy. The two are preparing for the wedding, and it seems nothing can overshadow their joy. But there is another one who pretends to the love of the heroine - spoiled and capricious Marat, a son of the factory manager. Marat is not embarrassed by the fact that Katya is not free; he is determined to get the unapproachable girl at any cost.
