Confined to a convent since the age of eight, Leonor dreams of freedom. She knows the outside world only through books, yet even these are forbidden. Her imagination and curiosity become her survival tools. She finds love, but her father opposes the union. Once free, she secures the new Queen's blessing for her relationship and dreams of travelling across Europe with her husband. The Queen, however, entrusts her with a mission: to unite the Portuguese and Austrian royal houses.
In Vienna, she discovers a world of masquerade balls and forbidden pleasures. Torn between love and royal duty, she flees to France. She strives to mend her marriage and regain the Queen's trust, but when her life is put at risk, she returns to Portugal. Inspired by humanist ideals, she fights for education and against the burning of books. She attempts to establish a school for girls and forms a secret society.
