A Mexican gang of bandits that have been robbing, murdering, and stealing cattle come to Denver to obtain the release of their leaders that were arrested and are being held in the Denver jail. Attacks on Denver force the U.S. Marshals to ask for help. U.S. Cavalry soldiers arrive to aid the the distressed and outnumbered lawmen, but they may be too late as the gang of outlaws converges on the town determined to free their leaders and burn Denver to the ground.
