At the beginning of the war, the Germans abandoned their saboteur in the USSR. The landing is unsuccessful - the spy is captured by the NKVD. When trying to escape, the saboteur, who turned out to be a Russian thief in law, accidentally remaining in the occupied territory, dies. To find the other spies participating in the operation, the Chekists have to turn to the twin brother of the criminal - the village teacher. (imdb)
