Dog trainer Pan Bin has the special ability to communicate with dogs, but is regarded as a madman by the world. He took over the commission from the pregnant woman Sun Yan and trained the Teddy "Master" who had bitten 18 people, but found that this dog was a "super male" and was born a bad breed. Pan Bin adhered to the dog training concept of "fighting violence with violence", but was misunderstood and accused by Sun Yan, and fell into a crisis of online public opinion.
