But when North Korean forces, backed by Russia and Iran, launch a surprise attack on Seoul, Jack finds himself thrust into a conflict that will determine the fate of nations.

As the conflict escalates and the specter of nuclear war looms, Jack realizes that saving Seoul may cost him everything. But in a city under siege, where every decision could mean the difference between survival and annihilation, he's willing to pay the price.
