In 2110, excessive emissions of greenhouse gases triggered a sudden change in the global climate. The earth became a frozen purgatory, and humans retreated to the underground "fire base" to survive. Meteorologist {Chen Xue} was shocked to realize during monitoring that the super volcano under the ice was about to erupt. The volcanic ash would block the sunlight, starting a ten-thousand-year ice age, and the base would eventually be destroyed. The only hope is hidden in the equatorial geothermal base, where the geothermal energy is enough to withstand the severe cold. Chen Xue led the team to drive an ice-breaking vehicle through ice crevices, a dead ice field full of giant beasts and predators, but at the end they encountered "ice natives" who regarded humans as the source of disaster. A negotiation for the survival of civilization begins in a frozen and desperate situation.
