 Army Lieutenant Devlin (Bill Elliott) is ordered to take Sgt. Frick(Myron Healey), Corporal Johnson(Robert Bray) and some troopers to break up a gang of gunmen hired by Frank Bullitt(Richard Reeves), leader of the cattlemen, to drive homesteaders from the range. Devlin s troop captures Bullitt and three of the hired killers: Fane(Gregg Barton), Karns (Denver Pyle) and Nixon (eugene Roth.) En route to Fort Jeffrey with the prisoners, the troop overtakes a wagon carrying Della Watson (Phyllis Coates) and her grandmother (Florence Lake), and Devlin reluctantly agrees to let the two women accompany his party. Meanwhile, Bullitt s foreman, Massey (Robert Wilke),has sent more gunmen to free the prisoners, and the disgruntled Lt. Frick has sold out to Bullitt.
