 In 1496, Juana de Castilla, daughter of the Catholic Kings, travels to Flandes to marry the Archduke Felipe de Austria, known as  El Hermoso  (The Handsome) and son of the emperor Maximiliano. Even though at the beginning this marriage obeys a political decision, later on passion and desire appear beneath the couple. Juana becomes queen of Spain when her mother and her older brothers die in 1504. However, due to the pressure of being queen and the discovery that her husband has many lovers, her mental health starts getting worse. Felipe, seeing his wife in these circumstances, makes the Burgos Court to declare the insanity of Juana and recludes her in the Monastry of Las Huelgas, proclaiming himself as the king.
