King Henry VIII's marriage to Catherine of Aragon is troubled as she has not produced a living male heir to the throne, having only one surviving child, Mary. Mary Boleyn marries William Carey. After the festivities, Thomas Howard, Duke of Norfolk and his brother-in-law Thomas Boleyn plot to install Thomas' eldest daughter, Anne, as the king's mistress, with the hope that Anne will bear him a son and improve the family's wealth and status, much to the disgust of Anne's mother, Lady Elizabeth. Despite knowing that being a mistress will damage her chances of a high ranking marriage, a reluctant Anne agrees to please her father and uncle.
While visiting the Boleyn estate, Henry is injured in a hunting accident indirectly caused by Anne. Urged by her scheming uncle, Mary nurses Henry. Henry becomes smitten with Mary and invites her to court, to which Mary and her husband reluctantly agree, aware that the king has invited her because he desires her. Mary and Anne become ladies-in-waiting to Queen Catherine and Henry sends William Carey abroad on an assignment. Separated from her husband, Mary begins an affair with the king and finds herself falling in love with him. Anne secretly marries the nobleman Henry Percy, although he is already betrothed to Lady Mary Talbot. Anne confides in her brother, George Boleyn, about the marriage.
