Four mysterious players are captured and tied up in a dungeon. They're the hidden players who are given a different set of rules to play. They must survive in the survival zone with bare necessities. One of them can enter the mansion and play as their spy until the Day of Ambush. On the Day of Ambush, they can drive out the other players and take over the mansion. Will they be able to survive in the wild until then?
