Lin Yan inherits the verge-of-bankruptcy Shiguang Zoo. Facing huge external debts, he always sticks to the original intention of "not forcing animals to perform". He and the brown bear Lao Hei, who can carve wood carvings, unexpectedly become popular on the internet, and successively rescue a group of animals that have suffered injuries, such as the elephant A Nan, the parrot Cui Yi, the otter Tao Tao, and the golden eagle Ling Feng. Everyone works together to resolve severe tests such as malicious suppression by peers, public opinion rumors, and operational crises, and finally builds the dilapidated small park into a national wild animal rescue and science popularization base, composing a warm and healing story of two-way guardianship between humans and animals.
