The shortest night of June 1941 shattered the lives of Senior Lieutenant Andrei Barkanov and his fellow border guards. Mortally dangerous battles with fascist hordes surrounding Soviet fighters from all sides, the death of fighting friends... And also - a constant gnawing anxiety about his wife and children remaining in a small Latvian village, long ago captured by the Nazis... And the Great Patriotic War veteran Ilya Petrovich is in danger in peaceful life. It would seem that there is no way out, but those for whom he was ready to give his life during the terrible war years come to the aid of the former front-line intelligence officer.
