The seven-day wilderness survival enters a white-hot stage. A six-person team is forced to separate to survive in a desperate situation with no food or medicine, and the secrets deep in the forest are uncovered step by step. Food traps, beast attacks, and human nature tests come one after another, and once side-by-side teammates begin to harbor separate intentions. When the rescue signal is finally sent, what awaits them is not hope, but a truth even more terrifying than hunger. 72 hours, not the end, but the beginning of a new round of survival.
