This tragic story deals with the short-lived reign of Mary Stuart. Surrounded by scheming Lords including her own brother, James Stuart, Mary seeks the comfort of Lord Bothwell, a close friend who shortly becomes a love interest. However marriage seems impossible and Mary becomes coerced into marrying weakling Lord Darnley, heir to the English throne. Meanwhile the queen of England, Elizabeth Tudor begins to feel insecure and plots to destroy the marriage, having Damley killed by the Lords. With the help of Lord Bothwell, Mary remains on the throne and soon they marry, only to be separated 20 days later when Mary is made a prisoner and Bothwell forced to leave the country. Mary moves to England under the deceitful guidance of Elizabeth, and upon arrival is yet again made a prisoner. However Mary's legacy remains with the birth of her son who will one day take the English throne.
