The Montana Kid

Larson cheats Burke at cards, has him sign over the deed to his ranch disguised as an IOU, and then kills him in a supposedly fair gunfight. This sends Bill Denton into action and he robs Larson and his henchman Gabby until he has enough money to buy back the ranch. When Larson realizes he received his own money back, both Larson and his men and the Marshal go after Denton.
