After attending the graduation ceremony of her eldest daughter, New York fashion magazine editor Louise Rayton Morgan is placed under the care of her physician, Dr. Cannon, for an unknown nervous ailment. Louise's three daughters, Tess, Alix and Ilka, suspect that their mother, who divorced their father Charlie, a newspaperman, years earlier, is merely suffering from loneliness and heartbreak. Having been shielded from the fact that their father was a poor provider and deserted their mother, Louise's daughters conclude that what their mother needs is a forced reconciliation with him. Soon after their mother leaves for a vacation in Cuba, Tess, Alix and Ilka pay a secret visit to Charlie's employer, Robert Nelson, who happens to be the thirteenth richest man in America. Determined to get their father recalled from his overseas assignment, the girls tell their story to Nelson. Tess wins Nelson's admiration by singing a special song for him, and he agrees to help the girls get their father back. Meanwhile, on board a cruise ship bound for Cuba, Louise falls in love with famous pianist and orchestra conductor José Iturbi. A romance blossoms, and the couple marry as soon as they reach Cuba. A short time later, Louise returns to New York, and is about to tell her daughters that she has remarried when they announce that they have arranged their father's return. Upset by the news, Louise visits Nelson, explains her situation and asks him to keep Charlie away long enough for her to introduce the girls to José. Nelson understands Louise's predicament and agrees to keep Charlie at bay to give her daughters time to befriend José. Louise is delighted when José easily wins the admiration of her three daughters, but her joy soon turns to sorrow when the girls discover the truth and become resentful. Fearing that she may lose her daughters' trust, Louise separates from José. José, deeply in love with Louise, realizes that the only way he can win Louise back is to have Charlie return to America so that Tess, Ilka and Alix can see for themselves what a poor father he would be. Nelson agrees to help José, but Louise's daughters intervene again and manage to prevent Nelson from sending for Charlie. Unable to abide the girls's numerous entreaties and their meddling in their mother's personal affairs, Nelson berates them for denying Louise the happiness she deserves and demands that they leave his home. Tess, Ilka and Alix eventually realize their selfish behavior, and, after apologizing to their mother and José, they forge a reconciliation bewteen the happy couple.
