The Americans are swiftly closing on Okinawa, an island just south of the Japanese mainland. The Imperial command sends top generals and several army divisions to defend it at all costs. The mission quickly degenerates as vital resources and troops are diverted to other islands. After a civilian evacuation ends in tragedy most of non-combatants are forced to remain on the island.
