A secret unravels behind the porticoed doors of London's grandest postcode. Set in the 1840s when the upper echelons of society began to rub shoulders with the emerging industrial nouveau riche, Belgravia is peopled by a rich cast of characters. But the story begins on the eve of the Battle of Waterloo in 1815. At the Duchess of Richmond's now legendary ball, one family's life will change forever.

The story of the amoral beauty Becky Sharp, who defies her impoverished background to climb the social ladder, and her sentimental companion Amelia, who falls for a caddish soldier, presents a panoramic satire of Regency society.
