Entitled to inherit his deceased fathers estate and title, child aristocrat Benjamin Blake (Roddy McDowall) is instead kept as a bond-servant to his villainous uncle (George Sanders). When Blake, now a young man (Tyrone Power), is beaten for falling in love with his uncle's daughter (Frances Farmer), he escapes by ship where he learns of a pearl fortune on a South Pacific island. There, he leads an idyllic life with a native girl (Gene Tierney) until he is compelled to return home and recapture what is rightfully owed him.
