A Soviet intelligence officer was sent to the territory of pre-war Germany to check an intelligence network. The network has failed, he is sending information about the impending attack of Nazi Germany on the USSR. The GB does not believe him, they want to remove him and give him the task of personally verifying the reliability of the last appearance. He completes the task and, although contacts with him cease, he continues to act independently without the support of headquarters. Based on the story, the feature film “Unknown Pages from the Life of an Intelligence Officer” was shot in 1990.
