When soldier Robin happens upon the dying Robert of Loxley, he promises to return the man's sword to his family in Nottingham. There, he assumes Robert's identity; romances his widow, Marion; and draws the ire of the town's sheriff and King John's henchman, Godfrey.

Ex-soldier Frank Brayker is the guardian of an ancient key that can unlock tremendous evil; the sinister Collector is a demon who wants the key so he can initiate the apocalypse. On the run from wicked mercenaries for almost 90 years, Brayker finally stops in at a boarding house in New Mexico where — with the help of its residents — he plans to face off against the Collector and his band of ghouls, preventing them from ever seizing the key.
