Hunt-U.S. V is filled with action. A Mexican gang of bandits that has been robbing, murdering, and stealing cattle comes to Denver to obtain the release of their leaders, who 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 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.
