Dynamite Canyon (1941)

Duke Rand, leader of a gang of desperadoes, has murdered rancher John Reed, and Arizona Ranger Colonel Blake, the only two men other than himself that knows there are large deposits of copper on the Reed ranch. He knows the blame will be placed on the cattle-vs-sheep range war. Tom Evans, posing as a wanted outlaw, Ed 'Trigger" Jones, works his way into Rand's confidence. The latter sends "Trigger" to make trouble for Midge Reed, the murdered man's daughter. Tom, as "Trigger" devises a plan to trap Rand but it backfires and he soon finds himself between two fires.
