Land of the Lawless(1947)

Johnny Mack Brown goes up against a female boss villain in this unusual Western from Monogram. Hired to look into dirty dealings in the town of Medicine Flats, Johnny learns that Kansas City Kate (Christine McIntyre), the owner of the Golden Spur Saloon, has been waging a war against local prospectors, one of whom is found murdered. Not appreciating Johnny's interference, Kate has her henchman Cameo (Tristram Coffin) take a shot at him and when that fails, hires a notorious gunslinger, the Cherokee Kid (I. Stanford Jolley).
