Chu Nan, a dog trainer who can understand dogs, takes over the 50-kilogram Husky Cuihua, a pregnant woman Shi Zhenxiang who has bitten 8 people. Chu Nan discovered that Cui Hua was wise and had the desire to hurt others, so he used violence to control violence. However, Shi Zhenxiang made a video and accused him of animal cruelty, and was retaliated by Internet violence. Cuihua eventually bit Shi Zhenxiang and sent him to the hospital. After the truth came out, Chu Nan clarified his grievances and became popular with his professional dog training knowledge. He also dealt with Shi Zhenxiang's subsequent revenge and the pressure to marry in his life, adhering to the concept of scientific dog raising.
