This moving film tells the story of an extraordinary day in the life of a provincial family whose father and son have planned a one-day trip to Moscow. The trip is intended to be a birthday present for the nine-year-old boy who is going to see a large, unknown city for the first time. At the same time, it is a celebration for his father, for whom Moscow represents an inaccessible romantic dream, a city where everything is perfectly arranged and organized. However, although the plan had been carefully thought out, the celebration is unexpectedly disrupted at the station by a cumbersome object for traveling, namely a street lamp, which the sister-in-law insistently and indifferently forces our heroes to transport. Moscow is taught by the main character's nephew, who has long since left the austere guardianship of his mother and who, forced to overcome his provincial inertia and distraction, organizes his life in a rather original way. So, when his family members bring him this inconvenient and useless lamppost, he will refuse it without ceremony.
In these conditions, the main character of the film, with his provincial clumsiness and his lack of sense of direction in an unfamiliar city, and in addition overloaded again with this lamppost, which the sense of responsibility forbids him to get rid of, finds himself unable to stay within the narrow limits of his travel plan. Our heroes are very late, the gigantic American shop windows do not arouse any interest in the child, they cannot find the Red Square, and in addition they lose the lamppost and must search for it by overcoming a number of difficulties that bring the father's singular romantic views back to the surrounding reality.
And it is only in the evening, when this apprentice connoisseur of Moscow understands that responsibility towards his family is more important than the endless whirlwind of worries and he finds his lamppost; when the father, overwhelmed by his inability to organize his day, understands that this trip is only the first and that there will be others; when the boy is overjoyed after his unusual birthday, we realize that it was "for real" a happy day in Moscow.
