Lois Ames is devoted to her job as the editor of a magazine, and her wealthy husband Fred is equally dedicated to polo and parties. Lois's long hours drive her secretary to quit, and she replaces her with Tom Sheridan, who happens to be in the office demonstrating a rowing machine. Tom likes the work and continues to advance until he is indispensable to Lois. Ruth Holman, Tom's fiancée, is jealous of Tom's relationship with Lois and with some reason, as he is falling in love with her. In the meantime, Fred is having an affair with Ann Le Maire, a woman whose interests are closer to his own. Because he feels his love for Lois is hopeless, Tom quits his job and plans his marriage to Ruth. Lois tries to patch things up with Fred, but he suggests that they divorce instead. On Tom's last night, Lois keeps him working late. Ruth is furious and storms up to the office where Lois and Tom are dining. She threatens to tell Lois's husband about their relationship, which leaves the way clear for Lois to announce her pending divorce. Ruth breaks off her engagement to Tom, and he immediately asks Lois to marry him.
