Prince George, second son of King Edward VII and grandson of Queen Victoria had never expected to become King of England. But his life changed completely in 1892 when his eldest brother Albert Victor, the Duke of Clarence, died on the eve of his wedding to a German princess, Mary of Teck. As a dutiful English prince, one who was now heir to the throne, George married the German princess himself. So began the long royal partnership of George and Mary. But what began as a marriage of convenience between two painfully shy, emotional people, would blossom into an enduring love. More than a royal love chronicle this is the real story of the birth of a new royal dynasty and how King George (accused of being pro-German) was forced to change the name of the royal family to Windsor.

Using stunning archive film from the early 1900s, this film is the story of George and Mary, the sober, awkward couple, who as king and queen of Great Britain steered a steady course through the tragedy of World War One, economic recession and, for a time, a genuine republican threat to the throne.
