The United Nations anti-drug organization and the Chinese and Myanmar police jointly launched a strike against the drug trafficking organization led by the Saka Group, which was attempting to smuggle drugs through China to the rest of the world. Forest police officer Zheng Hongfeng is unexpectedly caught up in a major drug trafficking case and finds himself in a dangerous situation. To avenge his colleague who was killed by the drug traffickers and to prevent drugs from entering China, he teams up with Wu, who has been deeply harmed by the traffickers. Together, they confront the drug traffickers in the dense border forests, ultimately cooperating with the anti-narcotics special forces to destroy the drug dealers' stronghold.
