The life of Henry Orient, a New York concert pianist with more ego than talent, becomes completely disrupted when Valerie Boyd and Marian Gilbert, two 14-year-old schoolgirls who delight in romantic flights of fancy, decide that they are in love with him. Henry's affair with Stella, a married woman, is ruined by the constant appearance of the two girls, who Stella is convinced are teenaged detectives hired by her suspicious husband. Marian's divorced mother is devoted to her child, but Valerie comes from an unhappy home dominated by her self-centered and adulterous mother, Isabel. The situation worsens when Isabel discovers a scrapbook compiled by the two youngsters in their passion for Henry. Misconstruing the situation, Isabel barges into Henry's apartment and accuses him of seducing Valerie. She is easily convinced of his innocence, however, and readily succumbs to his charm. Valerie learns of the illicit affair and, shattered, returns home only to be told by her mother that she must never see Marian again. Mr. Boyd, however, decides to leave Isabel and start a new life with Valerie. After a trip to Europe, Valerie visits the Gilbert apartment and resumes her friendship with Marian. Now the girls have a new interest in boys to replace their former taste for fantasy.
