Based on an autobiography of a senior intelligence officer of Soviet GRU. It is a Polish-German-Ukrainian co-production and it is interesting that it is now very difficult to get a copy of this film - too close to the inconvenient truth? If you can get it with English subtitles - definitely see it, it is on pair with the best espionage thrillers. It shows a normal person being gradually pulled into ever more secret circles of the Soviet Military Intelligence, where to remain human becomes increasingly difficult. The rules are cruel, nobody is your friend - even if they appear to be so - and everyone is watching you. Top acting, well told (real) story, and a true and disturbing picture of life behind the Iron Curtain make this one a top movie. Janusz Gajos is excellent in his role - he stars as an experienced GRU officer, a mentor for the main character.
