Pan Jingquan (played by Zhang Guoqiang), the first lawyer in Jiangnan, is a "lawyer" who dominates Qingxin County. He is eloquent and can confuse right and wrong. Everyone in the county knows him, and even the county magistrate is afraid of him. Teacher Zhang Siwei (played by Guo Jinan) is a righteous man who believes in Confucianism. His greatest ideal is "no lawsuits in the world". He is extremely disgusted with Pan Jingquan's daily actions. Zhang Siwei accidentally revealed the secret of Pan Jingquan's son Pan Erming. Pan Jingquan felt humiliated and tried every means to retaliate against Siwei. Just when Siwei was trying to commit suicide, a woman accidentally saved him who was about to hang himself. The woman who called herself "He Huizhen" (played by Tian Ruini) regarded herself as a "benefactor" and temporarily lived in Confucius Academy. The sharp-tongued He Huizhen and the conservative and pedantic Zhang Siwei became happy enemies. A batch of valuable collections suddenly appeared in the county. Its owner turned out to be the famous lawyer Chen Mengji who had disappeared for 20 years. Will this famous person who once confronted Pan Jingquan show up? What is the true identity of He Huizhen, whose origins are unknown?
