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.

As night falls, the fight for survival has already begun. Shocked by their extreme situation, the students of Daitoa Academy resign themselves to what they'll have to do to get off the island. Some students want to cooperate, but others fall back on their own merciless killer instincts. The squad leaders begin to take charge as they look for a way to survive. But the leader of Squad 2 may be the biggest threat to his own squad!
