The Ranger and Tonto are scouting a campsite when they come across two old timers, Mosshorn and Flapjack having a duel. After breaking up the fight they go to Mosshorn’s shack to get water. While there they notice a large number of Red Gap mining shares that Mosshorn won in a card game. Three men, Silk, Moose and Matt are salting the Red Gap mine in the hope of luring suckers to invest when they discover a legitimate vein. Before they can take control they need to get the shares back from Mosshorn.
