The Ultimate Western Spoof. A town where everyone seems to be named Johnson is in the way of the railroad. In order to grab their land, Hedley Lemar, a politically connected nasty person, sends in his henchmen to make the town unlivable. After the sheriff is killed, the town demands a new sheriff from the Governor. Hedley convinces him to send the town the first Black sheriff in the west. Bart is a sophisticated urbanite who will have some difficulty winning over the townspeople.

A story set against the Mountain Meadows Massacre, the film is based upon the tragedy which occurred in Utah in 1857. A group of settlers, traveling on wagons, was murdered by the native Mormons. All together, about 140 souls of men, women and children, were taken. Amidst this, two young lovers-to-be, one a Mormon and the other one of the doomed settlers from Arkansas, develop a relationship in an atmosphere of suspicion and rancor.
