Crater City, New Mexico, is a bustling mining town brimming with the stench of men hungry to get rich the old fashioned way - killing the competition. Dennis Conroy is the owner of the biggest saloon in town, and he needs a few good sharpshooters to help protect surveyors laying out a route for a spur railine before his rival Hugh Thornton beats him to it. Joe Buckhorn's handy with a gun so he takes the job. Against his best advice, he'll also take a liking to the boss's daughter, which doesn't go over well with her father. Worse, Buckhorn starts wondering exactly what kind of man he's working for. Before the sun goes down much blood will be spilled and a lot of men will be blasted into the middle of next week. Joe Buckhorns aims to be sure he's not one of them.
