When a Man Loves

John Howard Bannister leaves England for Japan after breaking off his engagement to Gladys Lee. In Tokyo, John meets Yuri San, the adopted daughter of shopkeeper Takamura. Charlotte Heathcote, who wants to become Lady Bannister, follows John to Japan. When she becomes jealous of John's attention to Yuri, Charlotte writes a letter to John's father, Lord Bannister. When John is summoned home by a cable with the false news of Lord Bannister's failing health, Charlotte intercepts John's farewell note to Yuri and lies to her about John's motives. John realizes he has been deceived. Ando Masuki is refused Yuri's hand in marriage by Takamura who says that his daughter's blood is English. Ando tries to kill Yuri and Takamura, but John saves them. John brings Yuri to England as his bride, but Lord Bannister refuses to accept Yuri as his daughter-in-law until Sir Robert Eastbourne arrives with the news that Yuri is actually the daughter he gave up at birth.
