In Hangtree, Texas, any other day could be your last. For, on the heels of the Civil War, Hangtree is drawing gamblers, fast women and faster gunmen. Amidst the brawls and shooting, the land-grabbing and card-sharking, two men barely hold the boomtown together: Yankee Sam Heller and Texan Johnny Cross. Heller and Cross can't stand the sight of each other. And Hangtree needs them more than ever. Now, a Comanche named Red Hand leads a horde of warriors on a horrific path of bloodshed and destruction, with Hangtree sitting right in Red Hand's path.
