The Major Case Squad Six received orders from their superiors to mobilize and intercept a drug deal involving an international trafficker known by the codename Poison Flower. However, an oversight during the operation led to the death of Han Li, a former member of the squad, while Poison Flower escaped. The squad was reprimanded, and morale plummeted.
At this time, Chen Xue was released from prison after serving her sentence, but the truth behind the Sixteen Shots case remained unclear. Tong Lin led the squad in taking another look at the old case. As they struggled to investigate, they repeatedly ran into obstacles and threats. But the Major Case Squad Six refused to give up. By piecing together the clues, they finally uncovered crucial evidence and brought Chen Xue back to justice.
As they pursued the case, the squad also dealt with other compelling incidents unrelated to the main plot, including a terrifying kidnapping, a sudden murder, a bomb threat, a human-trafficking mystery, and a web of fraud. Even while handling these cases, the Major Case Squad Six never let up in its pursuit of the drug traffickers.
The squad's new members, Yang Lu, Li Shaocheng, Wang Yong, and Zhou Zhibin, each brought their own strengths to the investigations. Wang Yong used his sanda championship skills to overpower enemies in critical moments on multiple occasions. Yang Lu's perceptive nature offered fresh leads, Li Shaocheng's diligence ensured that no detail was overlooked, and Zhou Zhibin used his quick wits and flexibility to outmaneuver criminals.
In the end, after a fierce showdown with the traffickers, the Major Case Squad Six successfully captured Poison Flower and completely dismantled the international drug-trafficking organization, upholding justice.
