The extreme cold wave suddenly fell, modern cities were frozen overnight, traffic was paralyzed, energy was cut off, and natural disasters swept through, testing human nature. Su Lin, the head of the public welfare organization, used calmness and tenacity to organize the survivors to save themselves; fire rescue captain Lu Ran led the team to the front line, tearing open the passage of life with iron blood and courage. Selfish officials intercept supplies and unscrupulous media spread rumors. The two work together to fight against natural disasters and evil people, promote ecological reconstruction on the ruins, and realize their own self-worth in desperate situations. When survival becomes a "competition for luck" and when fashion becomes a useless decoration in disaster, they use their faith to ignite hope and let the flames penetrate the cold winter of the apocalypse.
