Bruce Wayne is invited to the ancestral Waynemoor Castle, of the Waynes in England, where he meets several distant relatives and encounters a ghostly knight bent on centuries-old vengeance. Bruce is forced to intervene as Batman in order to stop the "ghost" and finds out that it is no ghost, but the butler, who discovered a past murder and became insane with the belief that he was the reincarnation of one of the castle's founders. Batman captures the insane man and clears the centuries-old murder mystery, but finds himself still baffled by the apparent supernatural circumstances surrounding Waynemoor Castle.
