The heavy nuclear-powered missile cruiser "Peter the Great" fell from our times into the South Atlantic in 1982 near the territory of the Falklands conflict - a two-hundred-mile zone of the Anglo-Argentine war. The Soviet leadership disowned them, the British declared them pirates, and the ship's crew was forced to join war under the Argentine flag. But when US intelligence services learned about the unusual origin of the ship, the Yankees forced Argentina to refuse its help and tried to capture a valuable artifact. And the commander of the cruiser decided to go to the Pacific Ocean with the ultimate goal - the USSR Navy base in Vietnam (Cam Ranh). But first we need to deal with the Americans, who do not intend to retreat and are preparing a large-scale action to intercept the cruiser!
