Lin Xiu is reborn back to the eve of a catastrophic blizzard. Foreseeing the disaster, she resolutely sells her newly built large tile-roofed house in exchange for money, food, and coal, leading her family to retreat to a stone cave for shelter. As the blizzard strikes on schedule, the new house collapses, and her greedy brother-in-law's family suffers while also instigating outsiders to seize supplies. At this critical moment, the village head steps forward to protect Lin Xiu's family. Having endured life-and-death hardships, the brother-in-law and his wife repent completely, and the whole village puts aside their estrangement to fight the disaster together, vividly showcasing human choices under disaster: only by looking out for one another can they survive life-and-death tribulations.
