Istrebiteli Bande son (1939) BO

Three young people, two boys and a girl, Varia, who met at school, meet again a few years later. The young men have become fighter pilots and the young girl works in an architectural firm. One day, during a low-level training flight, one of them passed a train but noticed that the railway was cut off by a landslide a little further on; he succeeded in warning the driver who stopped the convoy just before the collision. At a popular party, his friend, who seems to have a more intimate connection to Varia, is injured in his eyes while trying to save a child who set fireworks rockets on fire. As he is doing a dual exercise, he finds he can't see it anymore. Varia only finds out the truth when she returns from a trip. His two friends urge him to consult a surgeon who decides to operate on him. The operation was successful, and he found his squadron reunited, along with his parents.
