Plot synopsis: Even in the 1970s, films were made in this country that emphasized not only the necessity to defend the impermeability of the Western borders by all means, but mainly rehabilitated the Stalinist era. Told with ridiculous patheticness, the story is set in 1951 and takes place in army circles, depicting the disputes over the most effective air defence of the border... It chooses to depict the working disputes between an experienced, but already mentally stagnant general and a young politruk who advocates a modern conceptual solution to the common task.
