The comedy concerns the tumult felt in the British royal family after it's discovered that an Australian farmer is the rightful king of England.

The film is inspired by the true story of Mike Hastings, who now bears the title of the 14th Earl of Loudoun. He lives in Jerilderie, New South Wales. His world was rocked when genealogists discovered Hastings could be the rightful heir to the throne, based on claims that King Edward IV was an illegitimate child.
