Special agent Michael, who is not at a loss for martial arts skills, is personally commissioned by his boss to infiltrate a gangster syndicate suspected of dealing in illegal weapons of war on a large scale. It's just as well that the daughter of a businessman could do with a bodyguard. Michael selflessly saves her life and is promptly hired as a bodyguard. It turns out that his ward is being blackmailed. Does this have anything to do with the weapons?
