Svetlana comes to her hometown to visit her father and decides to stay to look after him. Leaving a successful career in the capital, she gets a job at a local bank, which belongs to her classmate Anton. He was once Sveta's school sweetheart, and now the old feelings flared up again. Anton's mother dreams of becoming related to a major entrepreneur, Viktor Shmelyov, and wants Anton and Viktor's daughter Margarita to get married. Shmelyov supports this idea - no one knows that his financial situation is close to collapse, so he really counts on the "relative" help of his potential son-in-law. They join forces to discredit Svetlana and upset their relationship with Anton. But at the last moment the situation gets out of control.
