Hondo and Buffalo are sent by Colonel Crook to head up a sheep drive to provide food for the Apaches. Cattleman Ben Cobb is against it and hires Allie, one of the sheep drovers, to sabotage the drive. Cobb sends renegade Coro and his small band to kill everyone on the drive but they are no match for Hondo, Buffalo and the drovers. Cobb then sends two of his men to poison a waterhole. Hondo and Buffalo kill one of the men and capture the other during a gunfight. Hondo takes the captured man back to Cobb and interrupts a meeting intended to enlist other cattlemen against the sheep drive. Cobb jails Hondo but Buffalo manages to break him out. Cobb and the cattlemen attack in the morning but Hondo gets the drop on him and forces him to call off the attack. Allie then tells them of Cobb's plot to steal their land. The sheep are delivered to the Apaches.
