Travis Alexander Boone, a bronco peeler in Montana, just lost his job after six long years. In search of a place to store his bedroll before another cold winter closes all the trails out of Montana, Boone rides to Wyoming: Three hundred miles later, in Six Mile Junction, he meets Mary Agnes Canfield, the widowed owner of the Double Deuce, a small nearby ranch. He accepts her offer of board for a winter’s work, unaware that her feud with a nearby rancher, Wells Gorman, is near its breaking point. Gorman, in desperate need of water, must build a canal through part of Mary’s land to reach it through her late husband’s resting place.

When Mary Agnes refuses to negotiate, Gorman swears vengeance. It’ll be up to Travis Alexander Boone and his trusty long-barreled Walker Colt to deal with this embittered rancher and his horde of gunmen and saloon tramps.
