A spy is sent to Moscow. The task of the KGB is to neutralize him and thus prevent a revolt in a fictional state of Nagonia.

The film takes place in Moscow and in the fictional African country of Traziland, in particular, in its capital, Luisburg. The KGB becomes aware that there is a CIA agent working in Moscow under the code name Trianon, who gives the Americans information related to the situation in another fictional African country of Nagony, bordering on Traziland. In search of a spy, the KGB goes to Olga Winter, a researcher at the Institute of Economics.—Peter-Patrick76 ([email protected])
