British aristocrat Lord Jimmy Broadbent lives a carefree life with his new American wife, Sheila. When his teenage daughter, Jane, from his previous marriage arrives to stay for the summer, Sheila decides that Jane should be introduced to London society. Despite Jane's initial reluctance, she is thrust into the whirlwind of debutante balls and high-society matchmaking. Sheila is eager to find a respectable suitor for Jane and becomes overly enthusiastic in pairing her with the perfect match, David Fenner, a wealthy but dull young man.

Jane, however, has her own ideas about love and soon crosses paths with the charming but controversial drummer, David Parkson. As Jane gets closer to David Parkson, Sheila’s matchmaking efforts become increasingly frantic. Confusion and humorous misunderstandings arise as the social season progresses. Tensions build between Jane's desire for personal choice and Sheila's ambitions for her stepdaughter's social success.
