During the war, having lost his family, Alyosha ends up in an orphanage. He devotes all his free time to music, with the full support of his caregiver, Maria Pavlovna. Noticing Alyosha’s exceptional talent, the touring conductor Dobrynin adopts him and brings him to Moscow. Dobrynin is very pleased: his own son and Alyosha now study at the same music school.
