The story of the Old West's valley of violence!

A group of copper miners, Southern veterans, are terrorized by local rebel-haters, led by deputy Lane Travis. The miners ask stage sharpshooter Johnny Carter to help them, under the impression that he is the legendary Colonel Desmond. It seems they're wrong; but Johnny's show comes to Coppertown and Johnny romances lovely gambler Lisa Roselle, whom the miners believe is at the center of their troubles.
