At the Polaris VI International Base in Antarctica, the story of "extreme survival suspense" of scientific researchers is told: the long winter of six months in Antarctica has come. During the polar night, 10 scientific researchers stayed at the base and lost contact with the outside world. Afterwards, when the outside scientific researchers returned to the base, they were greeted by a catastrophic scene: many of the 10 people who stayed behind had died, one was missing, and two survived. What happened in the dark, frozen, and isolated base?
