The heavy nuclear-powered missile cruiser Peter the Great falls from our times into the recent past, into the South Atlantic and finds itself near the border of a two-hundred-mile zone of one small but very funny war. And willy-nilly gets into a fight.This event completely turned the history known to us, creating the possibility of preserving the Soviet Union. But the enemy is not asleep, and a military operation is unfolding that will affect several countries at once, clashing direct and eternally potential opponents of the "cold War fields". Warships, submarines, naval aviation will come together in a deadly battle. And the GRU special forces will be at the forefront of the attack.
