Operation Mekong

When thirteen Chinese crew members are found dead on two vessels in the Mekong River, and a large quantity of drugs is discovered aboard, the Chinese government assembles a special task force to investigate. The inquiry leads to a powerful and unpredictable drug lord who controls the region known as the Golden Triangle, where the river runs through territory dominated by traffickers. The team, led by the experienced officer Gao Gang, works with an intelligence agent, Fang Xinwu, and a small group of operatives drawn from the countries along the river's course. Their mission is to track down those responsible and bring them to account, despite the risks of operating in lawless terrain.

Dante Lam directed and co-wrote the film, which followed Unbeatable in his filmography and later led to further large-scale action productions. Zhang Hanyu plays Gao Gang and Eddie Peng plays Fang Xinwu, with Joyce Feng, Wu Xudong, Zhan Liguo and Liu Xianda among the credited cast of twenty-five. Made for around 30 million dollars, it became a major commercial success, earning roughly 174 million dollars worldwide.

On IMDb the film holds a rating of 6.5 from about 5,700 votes, while on TMDB it stands at 7 from a smaller pool of 286 votes. A critics' rating of 6.4 from eleven reviews places it close to the audience scores.
