St. Petersburg and Leningrad are two names of the same city and two eras. The film tells about the attempt of the younger generation to understand and realize the heroic past of the city, and at the same time the story of Elizaveta Pavlovna Novozhenina, who survived the Siege and the most difficult events in the life of Leningrad. The film is about how the city, its culture, spirit and history, unites the destinies of completely different people, sometimes unfamiliar and completely different from each other.
