Bi Yuntao, a top dog trainer, can understand the voice of dogs. When Liu Ruyan, a pregnant woman, brought a ferocious Alaskan that bit several people to train the dog, he saw through the vicious dog's cannibalism and persuaded it to euthanasia, but was kidnapped by Liu Ruyan's moral code and slandered as a dog abuser. Liu Ruyan was bitten after insisting on taking away the vicious dog, and even came to make trouble and demanded compensation. In the end, Bi Yuntao produced evidence to prove himself, and Liu Ruyan was also punished by law for provoking trouble and wounding someone with a knife.
