The heroines of the series "You Can't Marry and Stay Friends" are two pregnant women, Anna and Margarita. They meet in the maternity ward, where Anna gives birth to a beautiful daughter named Masha, and Margarita gives birth to a strong son named Roman. As a joke, the mothers promise to marry their children and go their separate ways. They only meet again twenty years later. Roman is now a computer programmer glued to his monitor, and Masha has pursued a career. The caring mothers want grandchildren, so they decide to fulfill their long-standing matchmaking plan.
