After saving a mountain man named Arthur Books from deadly gunmen, Clint accompanies him to a town called Scorpion's Tail for a drink and a good night's sleep. Only trouble is, Scorpion's Tail is a lawless nest of sin.
There's no rest for the wearyespecially since Arthur has the key to some lost silver and gold mines. Looks like the Gunsmith might strike it rich, if he doesn't get struck down by Scorpion's Tail first.
