On the day of the divorce, Shen Nanzhi was reborn. In her previous life, she was plotted by her husband's family to purge herself and leave the house. After the extreme cold apocalypse came, she was locked out and froze to death by them. Thirty days before the disaster, she did not cry or make a fuss, got compensation, sold her car to raise money, bought an abandoned cold storage, stocked up on food, medicine, and built a safe house. But the cold wave came ahead of schedule, and the city lost power and water. Panic buying, fencing, and medicine shortages broke out one after another. Her ex-husband's family begged to be taken in, and the supply boss secretly coveted her. Lu Linchuan, the retired rescue captain, became her most reliable collaborator. Under the Beigang cold storage, a strange voice came from the door that had been frozen for many years. Shen Nanzhi guarded the door and set rules, and gradually discovered that this frozen apocalypse may not be a natural disaster.
