King of the Belgians (2016) online

The King of the Belgians is on a state visit in Istanbul when his country falls apart. He must return home at once to save his kingdom. But a solar storm causes airspace and communications to shut down. No planes. No phones. With the help of a British filmmaker and a troupe of Bulgarian folk singers, the King and his entourage manage to escape over the border. Incognito. Thus begins an odyssey across the Balkans during which the King discovers the real world - and his true self.
