In this Spaghetti-western-like martial arts actioner, Texas Ranger J. J. McQuade (Chuck Norris) is up against the weapons-dealer Rawley Wilkes (David Carradine) after Wilkes kidnaps McQuade's partner and daughter and takes them to Mexico.
McQuade's personal vendetta is encouraged by the government because Wilkes is hijacking U.S. arms shipments for his illicit weapons deals and the government wants him stopped.
After the kidnapping incident, McQuade is assigned Kayo (Robert Beltran) a rookie patrolman, to accompany him in his fight, and he is also joined by FBI-agent Jackson (Leon Isaac Kennedy). Jackson and McQuade track down Wilkes' secret airstrip -- and that is when the fireworks begin.
Every weapon known to human technology is brought into the picture as McQuade, also armed with his lethal hands and feet, goes ballistic.
