Here’s the little-known story of an extraordinary, highly charismatic, and adventurous character, born in 1900 in Tsarist Russia. A member of the nobility, Boris Skossyreff was a Nazi collaborator, an “assistant” to the Queen of the Netherlands, but above all, he was the self-proclaimed king of the Principality of Andorra in 1934, quickly ousted by the French and Spanish authorities. Involved in major conflicts of the 20th century from which he always emerged unscathed, this enigmatic man was actually a professional con artist and forger, as well as a gigolo and organizer of orgies… This unprecedented documentary is based on a fascinating investigation conducted over more than a decade, in collaboration with an international team of historians and advisors.
