The Wyoming tinderbox of Muddy Gap is feeling none too friendly ever since the Grubbs gang tore through on a hellraising 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 in rawhide.,Smoke needed a break from driving a herd of remounts north when he showed up in Muddy Gap.

As if that wasn't trouble enough, Chief Iron Claw's bloodthirsty Cheyenne warriors have just appeared on the horizon.
