Heldorado

During the Heldorado Frontier Days Festival in Las Vegas, Roy Rogers (Roy Rogers), a Nevada lawman, travels out to help out his friend Gabby Whittaker (George "Gabby" Hayes), who founded the event. Someone is passing counterfeit bills at the casinos, and Roy is called on to help find the culprits. Roy gets to work, and in the process makes the acquaintance of a lovely heiress, Carol Randall (Dale Evans), who has been chosen as the Queen of the Heldorado.
