The play is based on a drug trafficking case, which is between fiction and reality. Although the characters and plots in it are mostly fictional, the profession of anti-drug police is really as dangerous as in the play. They are equivalent to dedicating their lives to the country, holding the idea of going back every time they perform a task.
In the play, Zhang was incorporated into the Qin Dou Anti-drug Detachment after graduating from the Public Security University. She is the assistant of Zheng Xiao, the captain of the anti-drug detachment. She is thoughtful and capable. Zhang's father, a superior, is also a drug policeman.
In 24 years, Zhang Xudong was seriously injured on a mission, and Li Gang, the undercover in that mission, also disappeared. Over the years, Zhang Xudong and Zheng Xiao have been looking for Li Gang. It is reported that Zhang is not her own daughter, but her father Li Gang. It may be that after Li Gang disappeared, he adopted Zhang and treated her as his own daughter. I wonder if Li Gang will appear again.
By chance, Zhang and Wang Xingjian, who just joined the anti-drug detachment, became partners. Wang Xingjian was originally a film policeman. Zheng Xiao took a fancy to him because he took part in an operation to catch drug dealers, and then transferred him to the anti-drug detachment. Wang Xingjian and Zhang jointly cracked many cases, which dealt a heavy blow to drug trafficking gangs.
Zhang and Wang Xingjian struck a spark in the process of fighting side by side. No sooner had they developed than Tang Xiaoran, Wang Xingjian's first love goddess, appeared. Who will Wang Xingjian choose? In fact, the ending is already obvious. Zhang is the hostess, and she will definitely come with Wang Yi. For Wang, it's just a beautiful memory.
