On the evening of May 9, 1945, when Moscow is noisily and cheerfully celebrating the Victory Day, a young girl agronomist Zina Sokolova and a sailor officer Lavrentyev meet in the compartment of the Moscow-Vladivostok train. The sailor takes the lively, direct character of the girl for windiness and frivolity. Sokolova also reacted frowningly and mockingly to the satellite.
