 Jimmy and Sheila Broadbent (Rex Harrison and Kay Kendall), welcome to London Jimmy s 17-year-old daughter, Jane (Sandra Dee). Jane is from Jimmy s first marriage to an American and has come to visit her father and the step-mother she has never met. While visiting Sheila has the idea of making Jane a debutante, an idea Jane resists. Difficulties range from Jane s apathy to being placed on the marriage block, the determined efforts of Sheila s cousin, Mabel Claremont, (Angela Lansbury) to win wealthy David Fenner (Peter Myers) for her debutante daughter Clarissa (Diane Clare), and Jane s attraction to David Parkson (John Saxon), an American drummer who plays in the orchestra at the coming-out balls.
