Decades ago, the fascist government of the Republic of Greater East Asia seized control of Japan. In order to terrorize the citizens and crush any possibility of rebellion, the government established Program 68--a savage military program where teenage students were sent to a remote island and forced to kill each other--also known as the Battle Royale.

After being banned 20 years ago, Program 68 is back, this time under the direction of a sinister government artificial intelligence. The troubled and misbehaving kids of Daitoa Academy's Class F have been chosen, divided into squads, given weapons, and commanded to fight to the death. Now friendships and loyalties will be tested, and only the strongest will survive.
