In 1957, a French student Pierre Duran arrives in Moscow for an internship at Moscow State University. Here he meets the Bolshoi Theater ballerina Kira Galkina and photographer Valera Uspensky. Thanks to these acquaintances, Pierre is immersed in the cultural life of Moscow, not only official, but also underground. For a year, Pierre has lived in Moscow for a lifetime, completely unlike everything he knew. But internship and acquaintance with different aspects of the life of Soviet people is not Pierre's only goal. He is looking for his father, a white officer Tatishchev, who was arrested in the late 30s.
