The year is 1860. The United States is inexorably heading towards civil war. Gold fever excites prospectors with wild dreams. Pioneers are pushing the western frontier further. Against these events, is the story of two rugged frontiersmen. They are friends - Trevor Kingman is a rancher who lusts for power and Jed Richardson is a modest man who hopes to carve decency into the western wilds.
Kingman's pursuit of political fame and fortune eventually splits the friends. The only link between them is the love that developed between Richardson's son, Jimmy D., and Kingman's daughter, Rose of Sharon.
When a feud develops between the two families, Bovey (Kingman's son) - in a moment of anger - murders Jed. Jimmy D., despite his love for Rose, decides to avenge his father's death. He sets out after Bovey, racing through the wilderness plains across Native American-held country. By a chanceful opportunity Jimmy D. joins the Pony Express mail rider service. It is through the Pony Express that he is able to ride across hostile territory in his vengeance mission. Eventually, in uncharted territory, Jimmy D. gets his revenge.[3]
