London, 1933. Her Majesty the Queen is sending Georgie off to Nice with a secret assignment—to recover her priceless, stolen snuff box from the disreputable Sir Toby Groper. Her Majesty’s trust is an honor, but an even greater honor is bestowed upon Georgie in Nice when none other than Coco Chanel asks her to model the latest fashions.

Unfortunately, things go disastrously wrong on the catwalk and before Georgie can snatch the snuff box, someone’s life is snuffed out in a very dastardly way. With a murderer on the loose—and Georgie's beau Darcy seen in the company of another woman—how’s a girl to find any time to go to the casino?
