The earth's magnetic field suddenly reversed without warning, the communication system was completely paralyzed, the navigation equipment turned into a pile of scrap metal, and natural disasters raged around the world. On the remote Antarctic ice sheet, a scientific expedition team that was on a glacier geological survey mission instantly lost contact with the outside world and was trapped in this desolate white desperation. Physicist Lin Xia carries unfinished geomagnetic research data, and guide and captain Chen Feng carries the trauma of past polar rescues. They must lead the team to survive in the severe cold of minus 70 degrees Celsius and the crisis of running out of food and fuel. When the aurora turns into a deadly radiation curtain, unknown creatures under the ice cracks make strange sounds, and suspicion and despair among the team members spread like a snowstorm. Lin Xia and Chen Feng can only put down their barriers and use scientific wisdom and wilderness experience to fight against this catastrophe, and find a way back to the civilized world amidst the chaotic pulsation of the earth's magnetic field.
