Someone's trying to get the guys out of a town where they are helping a widow run from the saloon left to her by her late husband, but they can't figure out who's doing it or why.

After an embezzling banker / murderer sets up Curry and Heyes to take the fall for his crimes, the boys try to clear themselves by playing on his greed with a salted diamond field.

While Curry drives a wagonload of dynamite across rugged country, Heyes hires on as a guide for two Englishmen searching for a tribe of giant redheaded Indians rumored to have lived in the area of Devil's Hole.
