After becoming a Supreme Court justice, Peter Graham is visited by Olive Martin, a singer from New Orleans, Louisiana, with whom he had an affair in his youth. Although Peter has been sending money to maintain Olive's silence and to support their son, she now sees an opportunity to join high society, and demands that Peter divorce his wife to marry her. Meanwhile, in Boston, Massachusetts, Olive's son, Harold, becomes engaged to Peter's daughter, Anita, but the young lovers are soon devastated by the news that they were both sired by the same man. Olive's dissolute brother-in-law, Thomas Donald, finds Peter on the brink of suicide and reveals that he is Harold's father. Thomas goes on to explain that Olive adopted the boy as a means to blackmail Peter. Harold and Anita marry, while Peter confesses to his wife and Olive leaves town.
