The heavy nuclear missile cruiser Peter the Great falls from our times into the near past, into the South Atlantic and finds itself near the border of the two hundred mile zone of one small but very funny war. And willy-nilly gets involved in 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, which will affect several countries at once, confronting direct and ever-potential opponents of the "Cold War fields" in a skirmish. In a deadly battle, warships, submarines, and naval aviation will converge. And at the forefront of the attack will be GRU special forces.
