Before the notion of the “It Girl” existed, Georgiana Spencer, the Duchess of Devonshire, was the personification of the term. Married at a young age in 1774 to the powerful Duke of Devonshire, she used her wit, feminine wiles and innate flair for fashion to become one of the most beloved and influential figures in British society and politics. That proud historical mantle – and the phenomenal matching hats – are donned with style by Keira Knightley. With an almost tactile sense of her character, she effortlessly embodies both Georgiana's charisma and her heartbreaks. And the heartbreaks are many. Thrilled at the prospect of being married to the duke, Georgiana soon realizes that her husband's heart is not to be won by allure or beauty. What her husband really wants is a male heir. But she crosses paths with Charles Grey, a former acquaintance who still carries a reckless torch for her.
