Two wanted outlaws. One hell of a story.

After a lifetime of robbing banks and holding up trains, Jimmy "Slash" Braddock and Melvin "Pecos Kid" Baker are ready to call it quits--though not completely by choice. Sold out by their old gang, Slash and Pecos have to bust out of jail and pull one last job to finance their early retirement . . .

The target is a rancher's payroll train. Catch is: the train is carrying a Gatling gun and twenty deputy US marshals who know they're coming. Caught and quickly sentenced to hang, their old enemy--the wheelchair-bound, bucket of mean, Marshal L.C. Bledsoe--shows up at the last minute to spare their lives. For a price. He'll let them live if they hunt down their old gang, the Snake River Marauders. And kill those prairie rats--with extreme prejudice . . .
