Xiaoyu returns home in debt to sell the old house. Her mother Zhang Cuihua falls from the second floor uninjured, but is actually zombified. Her uncle and creditors force her, and her best friend Pangda suggests live-streaming "Mighty Aunt" to make money. After going viral, Xiaoyu loses herself and treats her mother as a tool. Framed and cornered by the entire internet, her mother protects her with her spine during a landslide, and Xiaoyu painfully wakes up to become her mother's protector. At the moment of the iron cage and fire torture, the truth comes to light. In the explosion, two zombie mothers protect Xiaoyu. Everyone asserts there is no survival, and Xiaoyu returns to the old house with iron gloves. Leaving at dawn, a charred, grey-blue hand tremblingly puts down a plate of overcooked fried eggs, exactly the same as before.
