Episode 1 covers the first period of the Wars of the Roses (roughly 1453-1461), telling the story of Henry VI’s sudden illness and the impact that had on England. The drama portrays power struggles between Richard of York and Margaret of Anjou, as well as the emergence of Richard’s son Edward as a contender for the throne. Margaret Beaufort is introduced as a young mother and key member of the house of Lancaster; her husband Edmund Tudor dies in dramatic circumstances, leaving Margaret to take control of her destiny. The episode finishes with Edward’s triumph at the battle of Towton, the imprisonment of Henry VI, and the exile of Queen Margaret.

Episode 2 traverses the second period of the Wars of the Roses (roughly 1468-1471). We learn that while Edward IV has managed to retain the throne, he has also alienated many – most significantly his right-hand man Richard Neville, the Earl of Warwick. Like many in England, Margaret Beaufort has learned how to compromise with Edward’s rule; she has managed to keep hold of her lands and her life under Yorkist rule. Warwick proceeds to lead a rebellion against Edward, allying with the king’s brother George, Duke of Clarence, and his former enemy, Queen Margaret. For a brief period, Warwick achieves his aims and Henry VI returns to the throne - but Edward will not give up that easily. This episode ends with his return to England, his triumphant victory over Warwick at the battle of Barnet, and then over Queen Margaret at the battle of Tewkesbury. The episode concludes with Edward IV once again safe on the throne – while Margaret Beaufort’s son, Henry Tudor, is driven into exile.

Episode 3 focuses on the final period of turbulent conflict – and the story of the infamous King Richard III. In April of 1483, Edward IV dies unexpectedly and the future of England is once again thrown up in the air. Edward IV’s son and heir Edward V should be crowned king – but the prince’s uncle, the dead king’s youngest brother Richard III, takes control and takes the throne. Sky HISTORY details Richard’s power grab, but we also learn about those who joined forces to rebel against his reign. Margaret Beaufort comes into focus as a seasoned political operator, playing a leading role in the rising against Richard – ultimately securing a valuable marriage for her son Henry Tudor, and laying the foundations for his successful invasion and victory over Richard at the battle of Bosworth.
