The Wyoming tinderbox of Muddy Gap is feeling none too friendly ever since the Grubbs gang lure through on a hell raising rampage. And it's far from over. Because what the vicious Utah Jack Grubbs would really kill for just rode into town: Smoke Jensen... and a small fortune of rawhide. Smoke needed a break from diving a herd of remounts north when he showed up in Muddy Gap. Now, he's on the run again, headed for the Montana wilds - with Grubbs and his men shadowing his trail. As if that wasn't trouble enough Chief Iron Claw's bloodthirsty Cheyenne Warriors have just appeared on the horizon. It isn't long before a war between the white man's greed and the red man's fury turns the peaceful Bighorn Mountains into a simmering powder keg. Caught in the middle - with no way out - Smoke Jensen is just the man to set off the explosion.
