Valerie Carr (Anna Neagle) is a widow and the secretary to the editor of a women’s magazine. She is devoted to her two daughters, 17-year-old Jan (Sylvia Syms in her film debut) and 13-year-old Poppet (Julia Lockwood).
At a deb’s party, Jan meets Mayfair boy Tony Ward Black (Kenneth Haigh) and soon runs around with him and a bunch of jive-mad youngsters.
Valerie, promoted to editor of a teenage magazine, is attracted to novelist Hugh Manning (Norman Wooland) but prepares to put aside her own happiness to save Jan from herself and her unruly companions.
Tony becomes desperate for money, but Val refuses to give Jan her Post Office book to help him. Tony then tries to get the cash by force from an elderly aunt (Helen Haye), and the old girl dies from shock.
Both Tony and Jan are arrested for manslaughter, and Jan raves at Valerie and blames her for the trouble. So does the magistrate (Ballard Berkeley).
Jan is subsequently freed and ultimately realises the folly of her ways and the distress she has caused Valerie. She and Val are finally reconciled and Hugh hovers in the background.
Wanda Ventham appears in her film debut as Gina.
Released in America as Teenage Bad Girl.
