London, 1936. Inside the spectacular ballroom of the exclusive Buckingham Hotel the rich and powerful, politicians, film stars, even royalty, rub shoulders with the talented dancers from all around the world, who must enchant them, captivate them, and sweep away their cares. From behind plush curtains and discreet doors, the unseen staff of the hotel dream and listen - and watch. The storm clouds of war are gathering, and beneath the glitz and glamour of the ballroom lurks an irresistible world of scandal and secrets. Let's dance.
