Lawmen don't last long in the town of Doubtful, Wyoming Territory. The last one quit, another ended up in a noose, and one more was backshot by hired guns. But Doubtful has never seen the likes of the man known only as Cotton, who aims to take the badge for $125 a month, save himself a nice chunk of money over the next year, and be on his way. At least, that's his plan. Problem is, Cotton has just stuck his nose in the biggest hornet's nest in the territory.
