When Arizona Ranger Sam Burrack arrives in Mesa Grande with a few outlaws in tow, he finds the town in chaos. The sheriff's just been shot, and the new deputy--supposedly out in search of the gunman--is acting suspicious. Now it's up to Burrack to sort out who can be trusted and who needs to be put behind bars. But just as he starts putting the pieces together, a new kind of threat descends on Mesa Grande: Scalp hunters ride in...with a band of wrathful Apache warriors hot on their trail.
