 The suburban peace of the Bentley household is shattered when John Bentley (Jack Buchanan) is informed by his wife Stella (Brenda de Banzie) that their two married daughters, Pat (Jeannie Carson as Jean Carson) and Corrine (Susan Stephen) are in trouble and need funds to come home and bring their husbands, Peter (Nigel Green), a penniless Parisian artist and Barnaby (Hugh McDermott), a Texas cowboy, with them. And the youngest daughter, Gwen (Janette Scott), has tricked an American singer, Bobby Denver (Jerry Wayne), into visiting them on the pretext that it is the home of a noted British film magnate. When all the women in the household---including the maid (Joan Sims) ---fall for the singer s charms, Bentley consults a crackpot psychiatrist, Dr. Schneider (David Hurst), who almost succeeds in ousting, not the singer, but Bentley s wife, with his advice to Bentley to make her jealous by living it up with Pearl (Diana Dors), a showgirl recruited for the purpose.
