Paris in the 1980's. Dazed by prescription medication, a frail old American lady is a prisoner in a grey imposing mansion on the Bois de Boulogne. She was once the most famous woman in the world. Her name is Wallis, Duchess of Windsor. Her crime was to be a divorced woman who fell in love with a member of the British Royal family - the Prince of Wales, later King Edward VIII - precipitating his abdication from the throne to marry for love: the greatest crisis ever to befall the House of Windsor and a grave threat to the British Constitution itself.

Ten years after his death, attended only by a shadowy butler, we find Wallis in a twilight world where her beloved "David" has never really left her. As she refuses to relinquish the vivid memories of her extraordinary past, we soon discover why the incarceration of this vibrant and stylish woman is so vital to those whose lives she changed so dramatically. Her past is too full, the damage to her husband's family too great, her ostracisation too complete for her to be anything other than a dangerously loose cannon...

A stylish witty yet haunting new play on one of the most extraordinary and moving love stories of all time, set in the mansion which was visited on the very day of her untimely death by another woman to marry into the House of Windsor - Diana, Princess of Wales.
