She conspires with the Earl of Bothwell to assassinate her miscreant husband Lord Darnley.The story continues with her son James VI of Scotland (who, on Elizabeth's death, became James 1st of England), and the plot against his reign masterminded by the influential Catholic Robert Catesby - a plot planned by Guy Fawkes to blow up the Houses of Parliament in order to rid the nation of an oppressive Protestant monarch.
