Not many men get a second chance at life. But thanks to a chief U.S. marshal who needs their help, the bank-robbing duo of Jimmy Slash Braddock and Melvin Pecos Kid Baker are on the right side of the law. As unofficial marshals, they've agreed to pick up three prisoners from a Milestown jail and escort them to Denver. Sounds easy enough, until they learn the prisoners are an unholy trio of sadistic cutthroat killers known as Talon, Hellraisin Frank, and the Sioux called Black Pot. And they've managed to escape before Slash and Pecos even show up.
