Synopsis: Outlaw Jack Hammond and his gang terrorize ranchers to drive them off their land, which Hammond then purchases. When the gang attacks her husband, Mrs. Craig summons Crash Corrigan, a "range buster" she's known since childhood. Before Crash gets to town, Hammond frames Mrs. Craig's son, Charley, for the murder of a cattleman. Crash and his friend Alibi soon discover Hammond's hideout -- but then Charley goes missing.
