Het Engelse hof is samengekomen in het park van Buckingham Palace zodat er een officiële foto genomen kan worden. Een slordige belichtingsman laat een kabel op de vochtige grond slingeren en op het grote moment wordt de gehele koninklijke familie geëlektrocuteerd en er is geen erfgenaam voorhanden, buiten een zeer verre afstammeling in de Verenigde Staten. In Las Vegas accepteert barpianist Ralph met genoegen de 'rol' die hij moet gaan spelen. Ralph begint met veel goede wil aan zijn taak als koning, maar merkt al snel dat de etiquette aan het hof hem niet erg ligt.
Nee, helaas is King Ralph nog niet beschikbaar op Netflix in Nederland.
