The unusual adventure of two sisters – 26-year-old Margo and 38-year-old Katerina. They have never been close since childhood. As adults, they hardly communicate and know little about each other's lives. However, unexpected difficulties in Kateryna's life, which effectively knock her off her feet, and Margo's uncontrollable desire to win the heart of her beloved man bring the two sisters together. To carry out their plans, the sisters decide to switch places—Margo will pretend to be 38, and Katerina will become 26. The two women, who are complete opposites, must radically change their lifestyles, appearances, and habits, all for the sake of becoming happy and achieving their desired goals.
