Strangers are trapped in a room and forced to decide who would be the one survivor through a series of votes and debates about the worth of each human life.
In a massive, mysterious chamber, fifty strangers awaken to find themselves trapped with no memory of how they got there. Organized in an inward-facing circle and unable to move, they quickly learn that every two minutes, one of them must die…executed by a strange device in the center of the room.
Eighteen years after being pawns in a cruel game of psychological warfare, the survivors of an invasion face a new threat.
