In a mysterious polar ecological scientific research activity, five complete strangers with different personalities wandered into an inaccessible extreme cold restricted area after an accident. Faced with the unpredictable weather, the crises in the wilderness, and the huge differences between them, they formed the "Extreme Alliance" with humor and wisdom. In the test of life and death and inner struggle, everyone gradually opened their hearts, constantly broke through their own limits, and jointly faced the dual challenges of nature and human nature. In the end, they not only walked out of the wilderness, but also found their own unique values and life direction.
