Tordesillas, 1554. Seventy-four years old, Queen Joanna of Castile, called Juana la Loca (Joanna the Madwoman), is still mourning the loss of her husband who died a half century before. Joanna remembers with emotion the man she loved passionately, but who brought her ruin. She does not fear death, she says, because death would allow her to be reunited with her husband. Their story goes back almost 60 years.
