Lin Chen, an ordinary office worker, is caught in an aviation disaster while traveling and ends up stranded on a mysterious isolated island. With supplies scarce and one survival crisis after another, Lin Chen relies on his own abilities and wilderness survival experience to lead everyone in gathering food, hunting, building shelters, fighting off wild beasts, and enduring natural disasters such as wildfires and flash floods. During their exploration, they discover ruins left behind by earlier inhabitants and encounter a gang of poachers and smugglers. Using the terrain and homemade devices, the group outsmarts and outmaneuvers the criminals to protect themselves.
