Catherine of Aragon is the strong-willed young Princess of Spain, who has been promised the English throne since she was a child. She arrives in a gray, rain-lashed England with her glorious and diverse court, including her ladies-in-waiting Lina - a Spanish noble of African-Iberian descent - and the sweet and free-spirited Rosa. When her husband, Prince Arthur, dies suddenly, the throne seems lost to Catherine until she devises an audacious plan and sets her sights on the new heir, the charismatic and headstrong Prince Harry, who will one day rule as King Henry VIII.
