It tells the story of how the police arranged for SWAT team member Tang Shiyu to approach Zhao Wenjiu's sister Yaya in order to capture drug lord Zhao Wenjiu, so as to facilitate undercover entry into the drug trafficking gang. During this period, Zhao Wenjiu's enemy, the drug lord Chen Jiahua, sneaked into China for revenge. Tang Shiyu dealt with both parties, collecting evidence on the one hand and contacting Zhao Wenjiu's subordinate Huajiu on the other hand. After a series of twists and turns, Huajiu began to trust Tang Shiyu. With the help of Huajiu, Tang Shiyu cleverly conveyed information and successfully caught all the lawless elements. The story shows that as a people's policeman, it is not only necessary to distinguish between good and evil, punish evil and promote good, but also to step forward to rescue without hesitation when the people are in danger of their lives. As a woman, Tang Shiyu also showed extraordinary talent and the ability to turn danger into safety in the face of danger, which is no less than that of male team members, and led her own female SWAT team, cooperating with each other tacitly, handling quickly and accurately, demonstrating excellent psychological quality and business ability!
