In the 20s of the last century, a family of Jewish emigrants from the Russian Empire returns to the USSR from New York to work under a contract, but circumstances force them to stay. Another perky Komsomol family is enthusiastically participating in the construction of socialism in the young republic. Their children, by the will of fate, end up in the same class at a Moscow school. Against the backdrop of large-scale world events, the drama of ordinary people unfolds. The “March of Enthusiasts” was first heard in the film “The Shining Path” about the fate of the Soviet Cinderella. All characters, events and names are fictitious, possible coincidences are accidental and unintentional.
