Synopsis：This film mainly revolves around the anti-drug operation “Windcut,” which has been ongoing for six years. Five undercover police officers were deployed to Moon Village in a town in Yunnan, but within three years, three of them lost their lives, and the operation had made no substantial progress. The higher authorities decided to send He Zhiyuan (Xihongshi, Liao Shunjin饰) back undercover in Moon Village. The leader of the Windcut operation team, codenamed Windcut, and its members underwent special training before infiltrating Moon Village in batches. However, Yuan Xinhua (Cao Guoqiang饰) entered Moon Village directly without training, earlier than the others, and maintained contact with other Windcut team members. After He Zhiyuan entered Moon Village, he got in touch with Yuan Xinhua, and the two began to suspect the circumstances surrounding the deaths of the three police officers and the leader of the Windcut operation.
