By murder and intimidation, a crooked lawyer and his hired guns plan to take over Brackettville, the nearest town to Fort Clark and Colonel Mackenzie's Fourth Cavalry Regiment, insisting that the troopers remain outside the town's limits. The lawyer hopes to lure Mackenzie into gunfight with one of his gunslingers, but the Colonel counters by forcing a showdown on his own terms.
