Two Chinese commercial vessels are ambushed while traveling down the Mekong River in the waters of the Golden Triangle, one of the largest drug-manufacturing regions in the world. 13 sailors are executed at gunpoint, and 900,000 methamphetamine pills are recovered at the scene. Upon discovery, the Chinese government immediately sends a band of elite narcotics officers led by Captain Gao Gang to the Golden Triangle to uncover the truth behind the murders.
