The Mole follows a group of 12 players as they try to figure out who among them is The Mole, a saboteur trying to keep them from winning money. Players must decide who they think The Mole is and then learn as much about him or her as they can, because, at the end of each one-hour episode, the player who knows the least about The Mole is immediately "Executed" from the game. In the final dramatic episode, The Mole is revealed and one of two final players wins a substantial cash prize.
