Prairie Raiders

Steve Bolton, a Department of the Interior agent, has given young "Bronc" Masters a lease to 50,000 acres of range land. Several months later "Bronc" discovers a strange notice on the land, warning off trespassers. He thinks that Steve has leased the same land twice, grabs a gun and heads for town, although his level-headed girl friend, Ann Bradford, attempts to stop him. Steve pacifies him, and they both ride out to the range and discover a gang of men rounding up the wild horses.
