In his past life, a blizzard sealed the village, and Zhao Changhe guarded his brick-tile house, only to watch helplessly as his family was buried by the collapsed roof. Reborn three days before the snowstorm, he decisively sold his house at a low price, took his wife, children, and elderly mother to move into an abandoned cave dwelling, and preemptively stockpiled coal and grain while reinforcing the cave door. Facing the incomprehension of his relatives and the mockery of the villagers, he only sought the safety of his family. But when the wind and snow engulfed the village, the brick-tile houses collapsed one after another, and the warm cave dwelling unexpectedly became a sanctuary in everyone's eyes. The tests of snatching coal, ramming doors, family affection, and interests followed one after another; this time, he must protect his family and also guard his own conscience.
