Joe Armstrong, an orphaned drifter will little respect for much other than martial arts, finds himself on an American Army base in The Philippines after a judge gives him a choice of enlistment or prison. On one of his first missions driving a convoy, his platoon is attacked by a group of rebels who try to steal the weapons the platoon is transporting and kidnap Patricia, the base colonel's daughter, who happens to be along for the ride. Joe rescues Patricia and gets her safely back to the base, but everyone else in the platoon is killed, leading his superiors to conclude that Joe is guilty of cowardice, collaboration or simple incompetence. At the same time, the rebel leader vows revenge against the serviceman who disrupted his plans, and sends an army of ninjas to assassinate him and bring back Patricia. If he wants to survive and save the girl, Joe's going to have to draw on every last ounce of his training.

Five men wake up in a locked-down warehouse with no memory of who they are. They are forced to figure out who is good and who is bad to stay alive.

Joe is a professional hit man who picks someone off the street to do his errands, and after he is finished kills that person. His next assignment takes him to Bangkok, and as usual, he finds a street-wise guy named Kong to help him. After Kong has a close call and learns who Joe is, Kong asks him to train him and he does. Joe also meets a local girl who is deaf and spends time with her. However, Joe has a hard time keeping his other life from her. It also appears that the person who hired Joe, breaks his rule of complete anonymity and tries to find him.
