The only problem is &quot;The Triumphant,&quot; the submarine carrying the torpedo, is out of communication range and no one can confirm if the cancellation orders have reached the submarine.To prevent war, the government has tasked its two best experts, Haurée and Leroy, two strategic masterminds of the submarine fleet, to locate “The Triumphant” before time runs out and spread the latest information.
