Please answer the following question: I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Lady Jane Movie plot: Somerset has lost the power struggle with Northumberland and is executed. Northumberland, ruler of the realm due to Edward VI's minority, sees that the succession is key as Edward is unmarried. He will call on his friend Suffolk, Henry Grey, as Suffolk's wife, Frances Brandon, granddaughter of Henry VII, and their daughter Jane Grey, follow Henry VIII's daughters in the line of succession. Jane's great scholarship is made evident in a scene in which she interacts with and debates a priest who is a classical scholar. In the next scene, Edward notes "her learning is an example to us all."Northumberland advises Frances that Edward is dying and their plotting to deny Mary and Elizabeth the throne begins. The plan is to get Edward to modify the line of succession to exclude his sisters and to have Frances defer the throne to Jane. To consolidate power, Suffolk agrees to have Jane Grey marry Guilford Dudley, Northumberland's son. Jane is cold on the idea, suggesting Edward would disapprove. Jane is beaten by her mother for this remark. Northumberland convinces Edward that the marriage is necessary for the Reformation. Jane is convinced by Edward to marry Guilford "for me."Edward's health grows much worse. Northumberland asks the doctor to give Edward arsenic to keep him alive for a few extra days, which will buy Northumberland time to convince Edward to sign the document modifying the line of succession.Guilford is found in a pub and advised he is to be married. In his first meeting with Jane, she makes it clear that her priorities are study and prayer and he notes that he is the type that likes pubs and prostitutes. Their wedding night is absurd, as Guilford falls asleep just moments after Jane enters the bedroom.On a journey together, Guilford and Jane see commoners. Guilford offers one of them coins as alms. The commoner throws the money back, displaying that he wears the brand of a beggar, and yells "give us back our land," which could be a reference to the actions of Henry VIII, but more likely refers to... My question: Who was kept from the throne?
A:
Mary and Elizabeth
