Lawmen don't last long in the town of Doubtful, Wyoming Territory. The last one quit, another ended up in a hangman's noose, and one more was backshot by the hired guns at the Circle L Ranch. But the town of Doubtful has never seen the likes of the man who's 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. 

Cotton Pickens’s parents had a cussed sense of humor, but there’s nothing funny about the way the man can draw a gun. Now he’s in the middle of a mining camp district slowly being crushed under the iron fist of another misnamed, hardheaded fellow, Carter Scruples. With Cotton facing off against Scruples, a beautiful young woman caught in-between and a band of outlaws living high and mighty in a dry-docked Pullman Palace Car, the town of Swamp Creek is surely going to get blown sky high. 

Cotton Pickens made it through fifth grade. That and a tin star were good enough to make him the sheriff in the boomtown of Doubtful, Wyoming. And Doubtful's name is no accident. The saying around town is, "If you're a lawman, it's doubtful you'll last a day." Spoiled, brash King Bragg is going to hang for the murder of three men in a barroom. But King's arrogant father - and his beautiful sister - use their powers of persuasion to convince Cotton to look into the shooting. 

Cotton Pickens is feeling about as low as a man can get. Held up, robbed, and fired from his job as sheriff, things get even worse when someone murders Cotton's horse Critter. And it's all happening just as a flashy, fleshy stage company comes to town. Some folks demand the show be shut down for immorality. Some folks - Cotton included - sure enjoy the proceedings. But when a man gets stabbed to death, a bank safe gets blown up, and another county's sheriff starts imposing his will, Cotton realizes that a dastardly plot is taking over Doubtful.

It was a law Cotton Pickens never asked for and never wanted to enforce. But due to the vigilance of the Women’s Temperance Society, and the timidity of their businessmen husbands, the town of Doubtful, Wyoming, is going dry. As of January 1st. No exceptions. No turning back. Doubtful’s hell-raisers will not take this lying down, and Sheriff Pickens is fighting bootleggers and vigilantes when the next boot drops. The righteous women push through an even worse law bound to spark an outright insurrection.

Cotton Pickens got where he is by virtue of a quick draw and slow wit. He knows the difference between lawbreakers you have to lock up...and the kind you might as well just let go. Deputy Rusty Irons, though, ain't the sharpest tool in the shed. Someone kidnapped Rusty's mail order brides. They were probably doing Irons a favor, but a deputy in love is blind.
