A quiet stagecoach run between two Texas towns turns bloody when the riders are attacked by bandits and renegade Comanche. They are forced off the main trail and take cover in an abandoned bunkhouse once used for vaqueros when the land was part of a great estate. The stage was not only hauling a strongbox filled with Army pay, but a couple of dozen crates of new rifles for the cavalry. Unfortunately, the guns are useless as the team's ammunition is limited. Now the besieged stage riders have to join forces to fight off the surrounding desperados.
