Paladin goes after a wagon-master who led the massacre of his own wagon train. Rusty Doggett hides out in a town entirely populated by wanted outlaws. Finding someone to betray Doggett in the Bide-a-Wee Saloon is no problem, but crossing the death-line with his prisoner is very tricky. How much justice can Paladin bargain for in Hell ?
