Billy Blue is captured by the Apaches, who use him as a pawn in a bartering game to stave off an impending cavalry attack.

Although he denies pillaging an army weapons patrol, Apache Chief Morales anticipates a retaliatory attack by the cavalry and threatens the life of his hostage, Blue, unless his terms are met. John Cannon, who believes the Indians to be innocent of the pillaging charge, pleads for time, and vows to bring in the guilty parties in a desperate attempt to save his son.

Buck becomes involved in gold robbery by helping an old Army buddy.

A happy reunion between Buck Cannon and Army Sgt. Travis Winslow leads to Buck's hiring as a scout for Winslow and his detachment of men, who are escorting a military gold shipment through Apache country. En route, Buck learns that the Indians are not the only threat.
