The film is about the most intimate way of human communication, about letters. About individual thinking, reflecting the current life. A film about Petersburg, about letters that live their own lives and do not find an addressee. Among the protagonists are poets and porters, a sorter and a blessed woman, Hermitage restorers and cadets. The form of the messages is both poetry, and colors, and pictures of the morning and evening city, the image of the whole, where personal destinies add up to the polyphony of life.
