In the Golden Triangle region of the Mekong River, there is a section known as the "Gate of Hell." Two Chinese merchant ships were attacked by unidentified assailants while passing through this area. The Thai military later held a press conference, accusing the merchant ships of being involved in drug trafficking. Although it was claimed that all crew members had escaped, the bodies of 13 Chinese crew members were soon discovered, all brutally murdered. This shocking incident garnered significant attention from Chinese police. Gao Gang (played by Zhang Hanyu), the captain of the Anti-Narcotics Unit of the Yunnan Provincial Public Security Department, was assigned to lead a task force to Thailand. There, he teamed up with intelligence officer Fang Xinwu (played by Eddie Peng) to investigate. According to intelligence, the case was orchestrated by the notorious Golden Triangle drug lord, Naw Khar. Greedy and ruthless, Naw Khar posed a major threat to the safety of transportation in the Mekong River region. To bring him to justice, China, Laos, Myanmar, and Thailand launched joint patrols. While focusing efforts on dismantling Naw Khar's drug production bases, Gao Gang and his team ventured into dangerous territory, engaging in a fierce battle against the inhuman drug traffickers...
The film is based on the real-life Mekong River massacre.
