The protagonist Li Bin is a dog trainer who can hear the voices of animals. On this day, a female customer, Sun Yan, came to ask for help. Her Alaskan dog Qiuqiu had bitten many people, but she lacked discipline because of Ms. Sun's long-term pampering. Li Bin discovered that Qiuqiu was wild, had a high IQ and was at risk of learned aggression, so he suggested euthanasia but was rejected, so he had to accept it for discipline. During this period, Sun Yan mistakenly regarded the training as abuse and launched revenge on Li Bin.
