But the threshold they must cross is one of excruciating pain and -- in the face of torture -- not everyone is willing to play by the newly created rules. The group is ripped apart by infighting, secret alliances, double-crosses and shattering outbursts of violence. With the clock ticking down, the "one for all" mentality devolves. Just how far will each of them go to survive?
