The Arizona desert is a vast inferno, infested with murderous bandits from both sides of the border, rustlers, robbers and outlaws of every kind. But when the Apaches escape the reservation and go on a bloody, killing rampage, the army calls on one of their former officers to come back as a scout. They ask Dave Macklin to help them track down the renegades and subdue them. Macklin reluctantly agrees, but he soon finds out it’s a decision he may not live to regret.
