Four-year-old Mianmian can understand animal thoughts. Once, by pulling a crocodile's tooth, she lets her father Xu Cheng'an discover her extraordinary ability. Facing a zoo on the verge of bankruptcy, the father and daughter spend their last fifty thousand yuan to rescue Jin Dou, a timid Northeast tiger mistakenly thought to be fierce. Jin Dou becomes a hit as a socially anxious tiger, bringing visitors to the park. Mianmian subsequently helps the black bear Hei Tuan, exposes tourists' false accusations, recovers a mobile phone, prevents the feeding of spoiled meat, and assists veterinarian Wen Yining and behavioral consultant Shen Zhiheng in treating the elephant Duo Duo and helping the grey wolf Hui Wei. Xu Cheng'an withstands the pressure of acquisition, low-price customer poaching, and high-salary poaching of staff, improves management through professional assessment, training, and observation classes, and prompts his rival Cheng Shaofeng to admit his mistake.
