Kermit Maynard, the less-popular but arguably more talented brother of cowboy star Ken Maynard, heads the cast of Roaring Six Guns. Maynard plays Buck Sinclair, whose romance with heroine Beth (Mary Hayes) is hampered by the activities of her bombastic father (Sam Flint). Beth's dad covets a patch of government range land -- the same patch also coveted by Buck. The two men continue feuding until Buck wins Daddy's undying friendship by proving that the old man's business partner (John Merton) is a no-account crook. Budd Buster raises a few laughs (very few) as Maynard's comical sidekick.
