Blanche Auzello and her husband, Claude, the mistress and master of the Ritz, allow the glamour and glitz of the hotel to take their minds off their troubled marriage, and off the secrets that they keep from their guests --- and each other. Until June 1940, when the German army sweeps into Paris, setting up headquarters at the Ritz. Suddenly, Blanche and Claude must navigate a terrifying new reality. In order to survive, and strike a blow against their Nazi “guests,” they must spin a web of deceit that ensnares everything and everyone they cherish. But one secret is shared between Blanche and Claude alone --- the secret that, in the end, threatens to imperil both of their lives, and to bring down the legendary Ritz itself.
