Three Plus Three.

The Klyachev family lives in the picturesque town of the Golden Ring of Russia: writer Anton Pavlovich, his son Leonid, a blacksmith, and grandson Prometheus, who works as a lifeguard. The Larin family lives in the same city: active taxi driver Valentina Petrovna, her daughter Sveta, a tour guide, and an enterprising granddaughter, artist Yulia. Prometheus is convinced that Julia is a fraud. He uncovers one of her scams and turns Julia over to the police. The meeting of young people becomes fateful not only for themselves, but also for their relatives, who no longer hoped for personal happiness.
