'If you have a Wild, Unruly, or Undisciplined Daugher, two Ladies of Genteel Birth offer to Bring Out said Daughter and Refine what may have seemed Unrefinable. We can make the Best of the Worst'. When Amy and Effie Tribble, two charming but impoverished spinster sisters, lose out on an inheritance, they place this advertisement in "The Morning Post" and hire themselves out as professional chaperones. Vowing to prepare even the most difficult misses for marriage, the Tribble sisters will spend a London season on each client, educating them in their School for Manners. Felicity Baronsheath, their first assignment, turns out to be more of a challenge than they could have ever imagined. Not only is Felicity indifferent to the idea of marriage, she is also a spoilt brat! And when, despite their best endeavours, Felicity insists on remaining unrefined and hoydenish, the Tribbles begin to fear that her season - and their new business venture - will end in disaster.
