John Carteret has long been depressed and lonely, because at his wedding years ago, his bride Moonyean was murdered. He accepts into his house Kathleen, Moonyean's 5-year-old orphaned niece, and she quickly grows up to look just like her aunt. Kathleen meets and falls in love with a mysterious stranger from America, Kenneth Wayne. When John hears of this he is furious--it was Kenneth's father Jeremy who killed Moonyean. John carries his grudge against Jeremy to the new generation and threatens to ruin his niece's happiness, but he softens in the end.
