Forced to abandon his ancestral castle, William Tudor accompanies his granddaughter Irene to London, while millionaire John Kershaw buys the castle for his son, "Kit." Irene joins the Gaiety Theatre company, hoping that her lover, Owen, who has gone to Africa, will return and purchase the castle from the Kershaws. Mistakenly hearing of his death, she accepts the attentions of Christopher Kershaw, who intercepts a message from Owen. On their wedding night, Owen appears, and following Kit's death, they are reunited and the Tudor castle is restored to its heir.
