This film together with series No.2 of the same, is a great humanistic film about the blockade of Leningrad by German army during 1941 -1943.This is a story of fighter pilots defending Leningrad and citizens of same city under blockade where more than a half million citizens died because of hunger. Such a tragedy is so immense and would no way to describe it fully and exactly but can only be symbolized in some ways as in this film.Actress Lyudmila Gurchenko, who took a roll of young girl in Leningrad and also a volunteer for helping citizens, show her excellent ability to show a young girl's unbreakable dream even in such a desperate situation. She showed her superb ability as a musical comedy actress in the film "Carnival Night" (Soviet Film of 1956), and here she showed her another ability to take a dramatic and symbolic roll.Also this film might be a rare case for actor Michael Ulyanov who took part of a fighter pilot, since he later regularly took part of Soviet Army General Georgy Jukov in numerous Super scale Soviet WWII films.
