Texas Ranger Tim Bannon has been assigned to track down a gang of vicious outlaws who have been robbing and murdering all over south-central Texas. However, he has a problem. His old horse is no longer up to the task of traveling for days on end chasing renegades. Tim is forced to take the trail on a rented livery stable mount. Before he finds his quarry, he will discover that Rangers don't always have only two legs... some have four.
