Jane Dana (Deanna Durbin) is a cheerful teenager doing her best to survive the trials of youth. She's pursued by the eager Don Webb (Robert Stack), and the two seem well matched. Looming in the background, however, is Richard Calvert (Franchot Tone), a suave older man and a business associate of Jane's father. Unfortunately, Jane -- naive and untutored in the subtleties of courtship -- accidentally exposes her love triangle. The ensuing public scandal ushers her abruptly into adulthood.
