Tang Zhigao (played by Ma Junwei), who works in the Department of Justice, mainly deals with things such as spitting and illegal driving. In order to make a big move, he applied to be transferred to the government as a lawyer. Zhigao's father Dahai is very supportive of his son's work, but on the other hand, Dahai is addicted to gambling. He originally thought that he could make up for the previous debt by betting on horses, but who knew that this bet was illegal. The money won by gambling disappeared, and the debt was only repaid by his son Zhigao. Zhigao used the funds that were originally intended to buy a house, which made Dahai feel guilty and soon chose to leave the world. Zhigao, who became a lawyer, was dismissed from his position because of a slander.

Zhigao also met his first love girlfriend Xu Ying (played by Liao Bier). It seems that everything is getting better and better, but Zhigao and his police friend Yin Xiangming (played by Ma Guoming) are gradually involved in an incident, and there are many crises...
