After a brief mid-1940s burst of originality, Monogram's Johnny Mack Brown western series settled back into the commonplace with such entries as Flashing Guns. In this outing, Brown tries to save his pal Shelby (Raymond Hatton) from being thrown off his ranch by crooked banker Ainsworth (James E. Logan). To do this, our hero must prove that the banker is in cahoots with the local gambling boss (Douglas Evans).
