17-year-old Michael and his 5-year-old brother, Patrick, have been battling monsters in the Game for weeks. In the rural mountains of West Virginia - armed with only their rifle and their love for each other - the brothers followin instructions from the mysterious Game Master. They spend their days searching for survivors, their nights fighting endless hordes of 'Bellows' - creatures that roam the dark, roaring for flesh. And at this Game, Michael and Patrick are very good. But the Game is changing. The Game Master is leading Michael and Patrick to other survivors - survivors who don't play by the rules. And the brothers will never be the same.
