Two of Becky Warder's friends have come to talk to her, and are awaiting her arrival. Mrs. Lindon is jealous because Becky
has been spending a lot of time with Mr. Fred Lindon -- the Lindons have been separated for two (2) months. Becky has been trying to get Fred to go back to his wife, but Mrs. Lindon refuses to believe this, and tells Becky's
husband (Tom Warder) that the two have been together every day. Fred is a bit of a ladies man; Tom lays down the law and says that his wife can't see the man any more -- he trusts her, but is very afraid for her reputation. Becky, meanwhile, has ordered a new hat, but sends it back and pretends she needs the money for the hat, when she really wishes to send it to her ne'er-do-well (gambling addicted) father, whom Tom supports. However, she promises never to tell even little white lies to her husband any more -- an impossible commitment, given his sentiments and her feelings and actions, past and present, and perhaps, to come.
But her deceits, innocently and kindly as they are meant, come home to haunt her. Mrs. Eve Lindon (Fred's wife) comes over and shows the detectives' reports to Becky's husband, Tom, about the time that she (Becky) has been spending with Fred Lindon.
Becky's father shows up at their house, he with his housekeeper (and sometime finacee, who is willing to do nearly anything to marry him, including telling enough of the truth to Tom, eventually, to make, or break, the young couple's
marriage). So Tom finds out about all of Becky's lies, and he leaves her. She goes to stay with her father (who has gone home by this time). Her father says that breaking up their marriage is a terrible mistake, much like the one he had made about her mother and himself.
Her father telegraphs Tom that Becky is sick, but she refuses to go through with the deception, and swears an abhorrence of lies. The two young people are reconciled, as love rebuilds trust, and their future life together blossoms in prospect.
