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.
