When American heiress Pearl Saunders (Constance Bennett) marries Sir George Grayston (Alan Mowbray), everyone thinks it's a brilliant match. Sir George is delighted with Pearl's money, and Pearl is in love with her new husband's title in director George Cukor's adaptation of W. Somerset Maugham's biting stage comedy, Our Betters. Marital bliss quickly ends when Pearl discovers that Sir George has no intention of abandoning his philandering ways. She decides to match him affair for affair, plunging headlong into scandal and turning London's high society into her personal playground. But when Pearl's younger sister, Bessie (Anita Louise), appears to follow Pearl's example rather than her own heart, Pearl realizes the mistakes she has made in this sharp-edged, pre-Code classic.
