A military drama about the pilots of the Northern Fleet shows the war through the harsh daily life of the Arctic and the fate of the demoted navigator Bratnov. The Northern Fleet during the Great Patriotic War is a space where the harsh nature of the Arctic intensifies the already extreme tension of combat service. The heroes of the film carry out missions in the sky, daily facing risks and the necessity to trust those around them. Against this backdrop, the story of navigator Bratnov, who has been demoted and forced to prove his right to respect anew, becomes particularly noticeable. The film is built not around one spectacular feat, but around the internal journey of a person for whom military service becomes a test of character.
