After an extensive campaign, Colonel Mackenzie and his men manage to capture the leader of a ruthless outlaw band. Their victory is short-lived, however, because the bandit quickly escapes from the guardhouse taking the daughter of a visiting general as captive with him. Mackenzie must cross the Mexican border, sneak into the outlaws' camp, rescue the hostage and return to Fort Clark before the general realizes that his daughter has been taken captive.
