In Boston with her mother and grandparents, Susan poses as Sharon, while Sharon, as Susan, goes to Mitch's California ranch. Sharon learns that Mitch has since become engaged to a beautiful and much younger woman named Vicky Robinson (Joanna Barnes), a gold digger who intends to send Susan to boarding school after the wedding. Sharon secretly calls Susan with the news. Susan tells her to break up the couple, but failing that, they decide to prematurely end the charade and bring their mother to California. The next morning, Susan reveals the truth to Maggie and her grandparents. After a happy reunion, Maggie and Susan fly to California. Mitch, still unaware of the switch, is upset by Maggie's unexpected arrival until he learns the truth and is reunited with both daughters. Vicky, however, is furious that the glamorous Maggie is staying at the ranch.
