When 17-year-old Jane Broadbent comes to London to live with her wealthy father Jimmy Broadbent, her stepmother Sheila feels compelled by her own social aspirations to introduce Jane to society. Jane is bored by the debutante balls she attends and the young men she is introduced to, but she becomes interested in a drummer named David Parkson who has a reputation for leading young women astray. To complicate matters, an upper-class man with perfect credentials, David Fenner, relentlessly pursues Jane although she openly detests him.
