In Bottleneck Gulch, there’s a saloon where the owner is a crook of the worst order. When a second saloon opens, our crook isn’t happy that someone’s selling proper whisky cheaper than his own rotgut. To get rid of the competition, he calls upon an oversized gunman for hire, Phil Wire. But the killer runs afoul of Lucky Luke, who decides to take his place in order to clean up the town—only, not the way his employer expected!
