After divorcing, urban mom Qiao An'an returns to her hometown with her child and makes a living by livestreaming renovations of old houses. She personally builds high walls, sets up a vegetable garden and fish pond, and has barely transformed her shabby little courtyard into a livable fortress when a zombie virus suddenly breaks out. While everyone else frantically scrambles for supplies, she tears out the flower beds to plant greens, rips up the lawn to grow potatoes, and converts the swimming pool into a fish pond. With her daughter, she lives self-sufficiently while zombies surround the city. With no supernatural powers or portable storage space, this mother relies on her own hands and the courtyard she fortified in advance to carve out a way to survive in the apocalypse.
