Henry's uncle, Ambassador to Urbino, is assassinated by the French and Henry seizes upon this event to plan a war with France to establish his immortal reputation and seize back the title of King of France. More interested in his own ambitions, the Lord Chancellor, Cardinal Wolsey, manipulates the young king to propose a "Treaty of Universal Peace" with France instead. Thomas More, Henry's teacher and a humanist, is in favour of the treaty which further convinces a reluctant Henry to abandon his war plans. A summit is to take place in France, and—against Katherine's express wishes—their daughter Mary is to be betrothed to the Dauphin of France, also still a child. Meanwhile, Henry has a rival to the throne in the Duke of Buckingham, a blood relative to earlier Kings. Buckingham plots to murder Henry and thus grab the throne for himself, letting Thomas Boleyn and the Duke of Norfolk in on his plan. Boleyn's beautiful daughters Mary and Anne prepare to meet King Henry; meanwhile, Henry discovers that Lady Elizabeth Blount, his mistress and one of the Queen's ladies-in-waiting, is pregnant with his child.
