The Duke of York, nicknamed "Bertie" (James Wilby), was born as royal "spare heir", younger brother to the Prince of Wales, and thus expected to spend a relatively private life with his Scottish wife, Elizabeth Bowes-Lyon (Juliet Aubrey), and their daughters, in the shadow of their reigning father, George V (Sir Alan Bates), and next that of his elder brother, who later succeeded to the British throne as Edward VIII. However, Edward decides to put his love for divorced American, Wallis Simpson (Amber Sealey), above dynastic duty, and ends up abdicating the throne, which falls to Bertie, who reigns as King George VI. He expects to be, as constitutional monarch, little more then a figure head, but again, fate has other ideas: Nazi Germany proves to be such a formidable war challenger to the British Empire that the desperate nation looks to the royal couple as a comforting symbol of its unbroken spirit, a part they play with great success, while hosting chased monarchs and governments from continental Europe. After victory, life returns to normal, but pulmonary disease soon ends George's life, leaving the throne to his still young firstborn, who eventually reigns as Queen Elizabeth II (Elisabeth Dermot Walsh).
