Alexander Claremont-Diaz is the First Son of the United States. And then there's His Royal Highness Prince Henry of Wales. He's full of himself, condescending and an overall pain in the arse.

When The First Son and the Prince get into a public argument that threatens the relationship between US and Britain, they're set up in a public truce. Their damage control works and soon Alex and Henry find their friendship growing deeper than any of them could ever imagine.
