A group of survivors emerges from an underground shelter to find their city still in ruins, contrary to the promised beautiful landscape they saw in videos. Chelsea confronts a woman who defends Alan's warnings, insisting the giants are gone and the doomsday has ended. Fueled by a desperate desire for freedom, Chelsea rallies the people to establish a surface camp and leave their 'cage.' As they prepare to move, a giant senses their presence nearby, having waited for a meal, and discovers the open underground fortress.
