Very good movie. Start to finish action thriller. Wondering about so low ratings. Story of a mission of four nations against a dangerous drug mafia backgrounded at Laos, Myanmar, Thailand and China. Beautiful camera work with eye-catching photography of wood areas, valleys of Mekong river and surrounding. Story seems realistic not so sophisticated as other Hollywood movies based on a real event between drug mafia and police war which took 13 lives of China commando and a Police dog too! There are no big name in actors or no one is so powerful that story moving around him. A tension full climax will definitely impress you. Thrill, action and tension makes you bind till end without taking a sigh of relief. .No space for boredom here. I recommended this to them who love action and thrillers. Must watchable. It is pity for such good movie to see low ratings. It worth 8 or above. Me gives 8 stars and 1 extra for fascinating & classical outdoor photography.
