In the process of conquering the Antarctic, six members led by Cui Daoheng (Song Kanghao), the captain of the Antarctic expedition, and Mingzai (Liu Zhitai), the youngest member, discovered an Antarctic diary of the British expedition who died 80 years ago. The British expedition recorded in the diary is also composed of six members. With the appearance of this Antarctic diary, the expedition began to encounter all kinds of hardships. First strange diseases, then food shortage, then one accident after another, and the players died one after another. Finally, the expedition team came to the farthest place from the coast of the Antarctic continent-the "unreachable point" of 82 degrees 08 minutes south latitude and 54 degrees 58 minutes east longitude.
