Capt. Ranger Cordell Walker takes his colleague’s new, powerful car out for a test spin on Dallas’s streets. A bank robbery in progress is called in and the two head for the bank where a ranger present takes up the fight/shooting. Walker gets there in time to follow the getaway vehicle with two of the robbers. A corrupt scientist makes an extra copy of a new, vastly improved component for a missile guidance system so as to sell it. By accident the second component ends up with another employee and later his son, who then become the targets of a hard kicking Korean gang. Can Walker find the son and component in time? What about the one bank robber that got away?
