Résumé: The peace in Wonderment, Montana (a town founded by a group of ex-slaves freed after the American Civil War, the type of group historically known as Exodusters) is broken when a group of riders dressed like Ku Klux Klan nightriders attack. Among the townsfolk who fight back is Reno Jones, a man whose adventures have been depicted in more than a few dime novels.
The raids continue for days and the town makes a decision to hire gunfighters to protect them. A local Indian tribe agrees to ask a warrior they know to help. Reno Jones then sets of with a man named Marcel Fournier to contact others for help.
Jones locates the Rawhide Kid who is performing as a part of Buffalo Bill's Wild West show. Jones recruits both the Rawhide Kid and Kid Colt and the three of them leave together. Not long after this, a bounty hunter going by the name Gunhawk arrives and asks about the location of Kid Colt. Gunhawk is told where the three riders are going and rides after them.
