A former hero who has returned from another world is drawn into a deadly game with his classmates. Their ordinary school life ends when they are taken to an uninhabited island and told by a man in a tactical uniform that they must kill one another until only one person remains. The game is built on the idea that the strong will defeat the weak and only the toughest will survive. But the organizers do not know that one of their captives is a celebrated hero who has recently returned from another world. Once the game begins, their carefully prepared expectations are thrown off by his presence.
