Tiny yet prospering Benficklin, Texas, wants a clean, respectable town marshal to safeguard their pristine community from the kind of riffraff that turned neighboring Santa Angela into a raucous string of blood-spattered saloons and bawdy sporting houses. Former Texas Ranger Emmett Strong seems to be just the man Benficklin’s town fathers are looking for, once they're satisfied that his Chinese wife, Li, is "sufficiently civilized".
Reputations aside, Benficklin - not Santa Angela - is the town with the next scandal on its hands, when the ravaged body of a young, murdered Mexican girl is found lying in the middle of Main Street.
Initial signs suggest hard-drinking cowboy Quirt Langdon may have done the deed. Emmett, however, senses that things aren’t exactly as they appear. Nearby Fort Concho’s Captain Roderick Prentiss seems peculiarly interested in what is clearly a civilian case. And Santa Angela’s most eccentric resident gambler, Nate Chaffin, gives the impression he knows things he’s not telling. To top it all off, two of Benficklin’s leading citizens end up assassinated in their own backyard.
While local officials pressure Emmett to hastily hang either a suspect or a scapegoat, honor drives the former Ranger to seek true justice for the poor murdered girl, as well as for the two prominent citizens. Ill-tempered townsfolk, pilfered evidence, and somebody taking potshots at him and his wife make Emmett wonder whether he’ll live to unravel the mystery or become the next corpse folks find in the dusty streets of Benficklin.
