Whilst the young King Henry VIII basks in the pageants and games of his glittering court, his doting queen's health and fortunes fade. Henry's affection for his older wife soon strays, and the neglected Katherine decides to use her power as Queen to dangerous foreign advantage. Overseas battles play on Henry's volatile temper, and his defeat in France has changed the good-natured boy Katherine loved into an infamously callous ruler. With no legitimate heir yet born, Katherine once again begins to fear for her future.
