TASS Is Authorized to Declare...

Trianon (Boris Klyuyev), a willing mole agent for the Americans, is providing his CIA handlers in Moscow with information on Soviet supplies to the fictional African state of Nagonia which he obtains through his high-positioned expert job. KGB counterintelligence painstakingly identifies him. Trianon kills his fiancee who raised suspicions on his double life and commits suicide when arrested. KGB uses body double in order to secure apprehension of Trianon's CIA handlers. At the same time in Nagonia, Soviet counterintelligence agent Slavin (Yuri Solomin) risks his life assisting in identifyingTrianon and preventing local CIA resident Glabb (Vakhtang Kikabidze) from staging a coup d'etat in the country by pro-American General Ogano against ruling progressive president Grisso. Several foreign whistleblowers providing Slavin with information are killed by Glabb's order. As the result of successful KGB operation, the TASS state news agency issues a sensational news bulletin exposing the CIA plot. == Cast ==
