Portia and Emily meet to launch their daughters on an unsuspecting Society for the London Season of 1913. Both are determined that their offspring, Phyllis and Edith, will catch the eye of their friend May's son, a future Duke. If that were all, the Season would be a relatively simple affair, but since Portia is recently widowed and Emily is away from her husband, life is bound to get more interesting. Meanwhile, their arch-enemy Daisy Lanford, fallen on hard times due to extravagance and too many lovers, is busy launching American heiresses. However, her protegee, Sarah Hartley Lambert, whilst an engaging girl, is not the wild success Daisy hopes for. This is largely due to the machinations of Phyllis, who, having formed an unholy alliance with Edith, is intent on spoiling the American girl's chances. As always, the Season is fraught with dangers for both the young and the middle-aged, while the old observe, knowing it has all gone on before. It will be a minor miracle if all three girls find husbands before the end of the Season, and their mothers, not to mention Daisy Lanford, renewed happiness.
