Sheriff Clarence Barnes is the law in the small Wyoming town of Hillbrook. Anthony Cantare is a hired killer who finds his way to Hillbrook after a job-gone-wrong. Uriel is a man with no memories, and no place in the world, whose unending search for a lost past takes him to Hillbrook. These three strangers find their fates intertwined, even as a murderous militia group threatens to lay siege to the town. But this looming incursion may not be as great a threat to them, as they are to each other.
