The natural disaster that swept the world trapped a group of survivors with different destinies in the desolate "Boundary Islands". Without rescue and lack of supplies, they gradually formed a temporary team with no contact with each other. Everyone has secrets, motivations, and conflicts and bonds with each other. The pressure of survival inspires nature, and crisis events intersect with other surviving teams. Everyone's story lines collide with each other, there are both divisions and cooperation, and humor and self-deprecation resolve embarrassment and pressure. On the verge of death, they explore food, fresh water, and escape routes, uncover the mystery behind the disaster, and continue to battle wits and courage in the occasional contact with the outside world. After confronting nature, other humans, and their own weaknesses, everyone grows up in desperate situations toward redemption or self-destruction. In the end, the survivors worked together to overcome the final difficulty, win freedom, and gain a new meaning in life.
