At the end of the twenty-first century, five strange men and women from different backgrounds around the world were accidentally stranded on a mysterious desert island. The island has a harsh ecology, is full of mysteries, and is full of dangers. They are forced to work together to survive: facing scarce supplies, harsh natural challenges, threats from external wildlife and island mechanisms, weird weather, and internal conflicts and frictions. In the midst of crises, everyone uses humor to relieve tension, solve mysteries with wisdom, and grow complementarily between adventures and disputes. From the initial mutual exclusion, defense, and confrontation, to gradually opening their hearts to support each other, they break through themselves while digging for escape clues side by side. In the end, everyone discovered the ultimate mystery behind the dilemma-the island was actually a giant 'extreme survival experiment'. After unimaginable tests and self-reconciliation, the five people joined hands to open the door to return, and each gained a new life.
