In the late period of the Republic of China, warlords were fighting and the powers were eyeing each other. In Huangliang Hutong in Beiping, there lived dignitaries who were in charge of military, political, grain and silver. On weekdays, the clouds will meet, but under this seemingly calm appearance, there is a hidden crisis. Feng Ziding, an aristocrat studying abroad, and his father were suddenly killed after returning to China. His twin sister and the mayor's wife also committed bizarre suicide.

Yan Dapu saw Looking for You from the newspaper. He found Xiao San in trouble and asked him about Yao Dingliang's left hook. Only then did he know that he was left-handed. Yan Dapu explained to the director that the case of the mayor's wife hitting someone with a car was not that simple, and also proposed to detain the mayor's wife, which the director thought might be deliberately framed by Gao Ziang. Yang Fei, who claimed to be a witness, came to the police station and said that the mayor's wife was defending herself. Feng Xueyan received news from Zeng Zuo, and she wanted to wait until the trial. After the trial, Yang Fei swore by the famous words of God that she was telling the truth. She told the story that night, but she couldn't remember the shooting position clearly and the driver didn't see it clearly. Feng Xueyan thanked Zeng Zuo. She wanted to thank Yang Fei. Zeng Zuo only knows that she is a school teacher. After leaving the court, Feng Xueyan speculated that Yang Fei might be arranged by Gao Ziang, and Zeng Zuo got the final report of the case. Yan Dapu saw that Yang Fei was hired by Gao Ziang, and he felt that things were not as simple as he thought. Feng Xueyan woke up from her dream, and she remembered what happened that night. Li, a policeman who claimed to be a friend of Brother Yao, went to Komachi's house to get something back. Gao Ziang entered politics on the recommendation of Feng Xueyan's father.

Yang Fei said that he would sell one of his works for charity and donate the proceeds to Yao Xiaoqing. This work is a portrait of a girl.
