Following the death of her millionaire companion, May Fisher is disheartened upon learning that the entire estate is willed to Peter Morton, his nephew, who operates a mission on San Francisco's Barbary Coast. To get into his good graces, she takes the post as his assistant and for months works at his side, arousing the jealousy of Marion, Peter's fiancée; but she falls in love with him and refuses to claim the money when he advertises for May Fisher; and when her life is threatened, he realizes their mutual love and they are married. Her true identity, however, is revealed by Kingsley, the uncle's lawyer, and she confesses the truth to Peter, who--feeling betrayed--leaves her. But all is forgiven when she saves his life.
