When Blanche Probert, a neglected wife, reminds her husband Fred of their theater engagement one evening, he insists that he must work, and she invites his friend Edward Martindale to take his place. Later that night, Edward tries to kiss Blanche just as Fred returns home, and although she is innocent of any wrongdoing, her outraged husband divorces her. Fred rears his son, Fred, Jr., while Blanche takes custody of little Edith, and there is no contact between them for fourteen years. Having run out of money, Blanche is forced to become the proprietor of an elegant gambling establishment, "The House of Mirrors," which is frequented by Fred, Jr., as well as Edward's son, Tom Martindale. The young men are introduced to Edith as "Mr. Brown and Mr. Jones," and soon, both are in love with her. When Fred asks Blanche for Edith's hand, she recognizes his ring as the one she had given her husband years before.
