Franklin Kenneth Styne, or F.K. as he’s called, inherits an old castle from a distant relative. Upon arriving, he finds that he also inherited the Styne Castle staff, consisting of Egor, a hunchback experimenter who converses with a portrait, and Hilda, the no-nonsense housekeeper. An inept local constable and his beautiful niece stop by to welcome the young Styne, and to check him out. F.K., who has a penchant for poetry, soon finds himself entwined in the centuries-old mysteries of the Styne Castle!
