Legendary American frontiersman Kit Carson (Johnny Mack Brown) escorts a shipment of gold across the rough-and-tumble plains in this vintage 12-episode serial. Following an ambush on their convoy, Carson's friend Matt Fargo (Edmund Breese) ferrets the gold away, but fur trader Cyrus Kraft (Noah Beery) and his hooded Mystery Riders will risk all to grab the treasure.
