Having won the Battle of St Albans and with Richard Plantagenet on the throne of England, the Yorkists confront the Lancastrians.
Henry, to his wife's dismay, agrees to York's demand that he disinherit his son, Edward, Prince of Wales. Margaret vows to destroy York and his followers and enlists the support of Clifford and others to raise an army.
Margaret's forces meet with those of York in battle, during which York's youngest son, Rutland, is killed by Clifford. York is then captured by Clifford and Northumberland, taunted with details of Rutland's death and brutally murdered.
Edward and Richard are informed of their father's murder and unite with Warwick, who proclaims Edward the new Duke of York. They raise an army and defeat the Lancastrians at Towton. Clifford is killed and Henry, Margaret and their son are forced to flee north. Henry is captured and brought to London, where he is placed in the Tower by the new King Edward.
In France, Margaret and Warwick meet at the court of King Louis. News reaches them that Edward has married Lady Elizabeth Grey, in spite of his earlier betrothal, instigated by Warwick, to King Louis's sister, Lady Bona. This insult turns both Warwick and Louis against Edward.
Warwick pledges support to Margaret, releasing Henry from the Tower and re-instating him as King of England. Warwick leaves London to muster his army, during which time Edward returns and re-captures Henry.
The forces of Edward and Warwick meet at Barnet, where Warwick is killed. Margaret arrives in England with reinforcements. Her forces encounter Edward's for the last time at Tewkesbury, where, after much bloodshed, the Wars of the Roses seem finally to be over.
