In a famine-stricken mountain village, Nini chases a squirrel and gets hung upside down. She is rescued by Zhao Laoshi and Guizhi, and they become a family. She can understand the speech of birds and beasts, stopping a landslide, digging for yams, finding grain bugs in the granary, finding wild vegetables to escape a flash flood, saving a sow with dystocia, exposing Erzhu who stole and sold feed, and stopping tree-felling to protect the village houses. When winter comes, a pack of wolves repays the kindness by returning chickens; Zhou Wang and others kidnap Nini, and the wolves lead the way to rescue her; relief grain carts get stuck in the snow, and the wolves pull a sled to save the grain deliveryman. In early spring, she stops fake chemical fertilizer, and with the autumn harvest filling the granaries, the family is reunited.
