Soon after the 1793 French Revolution's regicide of Louis XVII, a patriot rising preceding the 1795 French invasion sees the Orange dynasty's stadholder Willem V flee to England. After his death, heir Willem Frederik hopes to be restored and raised a king by Napoleon. Instead he gets to rule tiny German Fulda and looses even that, settling on a country estate with wife Mimi, mother, Wilhelmina of Prussia and even more ambitious son Willem 'Guillot'. The heir never finishes the Prussian academy, confused about his sexuality. After Bonaparte's Russian defeat, dad gets to reign over a reunited Low Countries kingdom of the Netherlands at favorable but constitutional terms as William I. Now Guillot is acceptable as fiancé for the British future heiress Charlotte, but Leopold of Saxe-Coburg outsmarts that. After Waterloo, where he's wounded, a Russian imperial princess's hand is arranged.
