With their glamorous lives, tragic misfortunes, and scandals, the members of the Monegasque royal family have been in the media spotlight for decades. Luxury, jet set, and games of chance … words that are synonymous with the principality’s ruling family, which surrounds itself with an aura of glitz and glamour like no other royal dynasty in Europe. This documentary features rare film footage of the royal family, including, for the very first time, an amateur film of the preparations for the marriage of Prince Rainier and Grace Kelly. We interview representatives of Europe’s high nobility, including Prince Eduard of Anhalt and Prince Heinrich of Hanover, Princess Caroline’s brother-in-law. For the first time on German television, Hollywood director Robert Dornhelm speaks of Grace Kelly’s last film project. There are also interviews with biographers and old friends of the House of Grimaldi, all of which provides an unusual insight into the history of this dazzling royal family.
