Martin Brady, who escaped to Mexico years ago to avenge his father's killer, visits Texas to arrange an armaments transaction for his Mexican boss, strongman Governor Cipriano Castro. During Brady's recovery in Texas, the guns are taken. As if things weren't complicated enough, the local Texas Ranger commander invites him back to his outfit. When Brady returns over the border, Castro is not only displeased that Brady has lost his gun shipment, but also about to join forces with Colton to attack the local raiding Apache Indians.
