Actress Jiang Mingtang is reborn, remembering the tragedy of her past life where her best friend Su Mianmian used sorcery to steal her fortune and suffered brutal harm. On the eve of a variety show recording, Su Mianmian asks for her birth date to exchange fortunes, and Jiang Mingtang writes the birth date of the variety show's pet pig Fubao on paper and hands it over. Kept in the dark, Su Mianmian initiates the fortune-swapping sorcery, and backlashes continuously befall her, causing her appetite and behavior to go out of control. Dissatisfied, she forcibly initiates the ultimate life-for-life swap, completely binding the sorcery to Fubao, while Su Mianmian's body gradually undergoes bestialization. Jiang Mingtang collects evidence, tears up the ritual's birth-date talisman, and saves Fubao. Su Mianmian completely turns into a pig.
