In old age, Admiral Oktyabrsky—the former commander of the Black Sea Fleet—was deeply shaken by the main defeat of his life: surrendering Sevastopol to the enemy, at a time when not all defensive possibilities had been exhausted. But fate gave him a rare chance to correct his mistakes—he can return to the past, one day before the start of the Great Patriotic War. Prepare the fleet and the main base for defense, prevent the loss of Sevastopol and Odessa. Will the admiral be able to make use of the chance he has been given? To fight, not to hide ships in secluded bays! To seek battle himself, attack the enemy without mercy and without pity! Lead the Black Sea Fleet with a course toward Victory!
