On the day of his wedding, Sir John Carteret's fiancée, Moonyeen, is killed by a jealous rival named Jeremy, leaving him emotionally devastated. Carteret spends three decades in seclusion, mostly communing with the spirit of Moonyeen, until he learns that her niece, Kathleen, has become an orphan. He adopts and raises the child as his own but is alarmed when, as a young woman, she falls in love with the son of Moonyeen's murderer.
