Roy Rogers plays a daring young Wild Bill Hickok in this wild west drama, who is stationed as a relay station agent, and must protect a shipment of gold. He decides to give the valuable goods to his friend Gabby (George Hayes) to help take the shipment to California. However, the plan goes south when a developing love triangle among Hickok, Calamity Jane (Sally Payne) and Louise Mason (Jacqueline Wells) causes the plan to be revealed man with villianous intent. Sent by a foreign government to steal the gold shipment, Nicholas Tower (John Miljan) is all too happy to hear of the plan, and sets about gathering his goons to raid the travelers. Despite the robbery attempt and romantic woes, Rogers still has time to sing a few classic songs, including "A Cowboy Wedding" and "Up and Down the Prairie."
