Ukraine during the German occupation in 1943. 12-year-old orphan Mitka earns a living in a tavern under a false name by playing music every night for the mainly German guests. He is accompanied in his playing on the violin by the pianist Yegor. Even beyond the music, he tries to be a friend and mentor to the boy. Mitka, however, finds it difficult to accept the budding friendship. This is because none of the people involved has any idea that Mitka belongs to a Jewish partisan movement.
