Nothing much happens in Peaceful Valley, Montana. And that's just how Sheriff Lucas Monk likes it. Aside from the occasional drunken brawl or minor disturbance out on the reservation, he hasn't had to resort to his fists or sidearm in years. That is, until mid-October, 1914, when the theft of a wooden cigar store Indian sets off a crime wave like nothing Lucas has ever seen. It's not long before the first corpse shows up, bringing the peace in the valley to a thundering end.
