Carol and John Townsend and their friends, Eric Schulte and Charlotte Hopkins, end a social evening by separating into two cars for the drive home. Eric rides with Carol while Charlotte and John ride together. Eric loves Carol despite the fact that she only has eyes for her husband. John, however, is having an affair with Charlotte. Carol begins to suspect this when she learns that John has lied about spending his afternoons on the polo field. She hires a detective, who informs her that John meets Charlotte at a secret apartment. Carol invites Eric to join her for the afternoon, leading him to believe that she will finally give in to his proposals. With Eric in tow, Carol knocks on Charlotte's door, and when she answers, pretends to have knocked by mistake. Eric is surprised to see Charlotte in a strange apartment and while she tries to explain, Carol confesses her "affair" with Eric in a loud voice so that John will be able to overhear her from his hiding place in the closet. John is furious and, as soon as Carol and Eric leave, rushes home. Carol and John quarrel over Charlotte and decide to divorce, to the distress of their daughter Janet, who plans a marriage of her own to Paul Smith. Infuriated by what she sees as childish behavior, Janet announces that after having seen her parents' marriage fail, she and Paul will live together without benefit of clergy. As soon as Janet and Paul leave the house, Carol and John follow them to a hotel. Paul and Janet agree to open the door to their room only if Carol and John forgive each other and reunite. When they agree, Janet announces that she and Paul were married in the morning.
