Dorcas, Texas, where Butler takes on a lone ranger's job of outwitting and combatting Thorne, the big man in the territory whose control had ended in death for many. Answering the summons of Mary Davis, whose father had been killed, Butler does not reveal his intentions or identity, tries to tie in with Thorne, and at the close gets his evidence and his enemies... A not too original outline for some straightforward shooting.
