The on-verge-of-bankruptcy Sunshine Zoo ushered in a new turning point due to rescuing a mistreated grizzly bear, Dazhuang. Faced with capital shortages, management crises, and external doubts, Zoo Director Lin Guo'an always adhered to his original aspiration, leading his staff to use love and scientific rescue to rebuild a warm home for injured animals. Daughter Lin Xiaoman unexpectedly acquired the ability to understand animal speech, allowing the heartfelt voices of more animals to be heard by people. From rescuing the grizzly bear to guarding the old elephant, macaques, and white lion, everyone worked together with one heart to resolve crises time and again, bringing the zoo back to life.
