Abstract: The past never goes away. It comes back again and again. Sometimes a fleeting vision, and sometimes like a “mushroom” of a nuclear explosion on the horizon. In 1987, as a result of the perestroika chaos, an unaccounted for atomic bomb was buried at one of the strategic airfields on the territory of Ukraine, which was considered lost. Nowadays. A former strategic aviation navigator lets slip about “not being accounted for” to the wrong interlocutor... The information immediately spreads in the world of cloak and dagger. Intelligence services, politicians and terrorists want to use “nobody’s” bomb for their own purposes... A disgraced Ukrainian officer and a young CIA agent who considers himself a hero of Tom Clancy’s novels stand in the way of enemies.
