The Mekong River, one of the major waterways of Southeast Asia, has suddenly turned ominously bloody. Two Chinese cargo ships, the Hua Ping, and the Yu Xing 8, are hijacked by eight unknown gunmen on a misty October morning. Shots ring out, bodies thrown overboard, and the Thai police afterwards find 900,000 amphetamine pills on-board; an intense international investigation is called between China, Thailand, Laos, and Burma to help recover the bodies of the victimized crews, and to bring vengeance and justice to those who committed the atrocious deed. However, things gradually turn ugly as mistrust envelops the case, where death could reveal itself one turn away.
