Twelve contestants on a reality TV show are sent into the woods to face challenges that will test the limits of their endurance. While they are out there, something terrible happens. But how widespread is the destruction, and has it occurred naturally or is it man-made? When one of the contestants stumbles across the devastation, she can imagine only that it is part of the game. But as her emotional and physical reserves dwindle, she grasps that the real world might have been altered in terrifying ways --- and her ability to parse the charade will be either her triumph or her undoing.
