Persecuted by hunters, Chi Gu, a mother fox, flees to Kaoshan Village, where Grandma Zhou comes to her rescue. Grateful for her kindness, she secretly protects the villagers time and again, standing against greedy evildoers. When a mountain flood and mudslide strike, Chi Gu spares no effort and sacrifices her own cultivation to protect every villager. As the years pass, this gratitude and kindness between humans and foxes continue from generation to generation in the mountain village.
