When Marshal Rattigan Fletcher failed to stop Jasper Minx raiding the town bank, the angry townsfolk forced him to leave Ash Valley in disgrace. Rattigan went west in pursuit of Jasper, and in the inhospitable Barren Plains he got a chance to put right his mistake.

Rattigan is hired to find out why men from the Bleak Point silver mine have been disappearing in mysterious circumstances. As Jasper now works at the mine, Rattigan doesn't have to look far for a culprit, but Jasper claims he's not responsible. With the miners siding with Jasper, Rattigan will need to rediscover his tarnished instincts as a lawman if he is ever to solve the mystery and bring his nemesis to justice.
