Armed only with a gun and a frying pan, Hoyoung Cheon must survive Battlegrounds: a battle-royale style game with 100 participants, where there's only one way to win: kill the 99 other players, all of them death-row convicts. Hoyoung has another objective besides survival, though—he must find an assemblyman who was captured while investigating the game, and is now an unwilling participant. Can Hoyoung complete his mission on an island with 99 people willing to kill to survive, and emerge the last one standing?
