A mysterious invitation is sent to the world's greatest chess players, promising a once-in-a-lifetime challenge at a secretive, high-stakes tournament. But when they arrive at the unfamiliar building, they quickly realize this isn't an ordinary competition. Instead of playing at a board, they are INSIDE the game. Each player assigned as a piece in a massive, life-sized chess match. They must move according to the rules of chess, and every blunder, sacrifice, or checkmate comes at a deadly cost. If a piece is "captured," the player is executed in real-time. The mastermind behind this game remains unseen, their voice echoing through speakers, challenging the players to prove not just their skills, but their will to survive. As alliances form and betrayals unfold, some begin to suspect that there is more to the game than meets the eye.
