Desperate to further her son's claim to the throne, Margaret Beaufort joins Warwick's rebellion against Edward. The rebellion fails and the traitors must run for their lives. Jasper Tudor escapes into exile, while Warwick and George sail for France. Elizabeth and Jacquetta turn to witchcraft to stop them, but it is Isabel who is punished.

Exiled in France, Warwick still plots to control the crown. His youngest daughter Anne is used to make an unexpected alliance, giving him command of a huge army. When Warwick lands in England, Edward must decide whether to fight or run. Terrified, Elizabeth escapes to sanctuary, not knowing if her husband is alive or dead. She gives birth to a longed-for son, but is in fear for her life as Warwick enters London.

Lancaster is restored to the throne, with Warwick in control. But rumours that Edward is returning with an army unsettle the court. Anne and Margaret of Anjou sail from France, uncertain they will reach Warwick in time to win. Divided families face each other across the battlefield. Can Elizabeth's witchcraft save her husband, or will Warwick triumph? As many fall in the battle, everyone's fortunes change forever.

The crown is secure, but there is no peace at court. Elizabeth suffers more emotional turmoil as she loses those closest to her. Margaret Beaufort plans a political marriage to bring Henry home from exile - but has she met her match in Lord Stanley? Anne's marriage made her a traitor, so she is handed into George's care. His motives for keeping her away from court are questioned by Richard, who fears for Anne's safety.

George's anger at losing the Warwick inheritance and his failure to capture the crown resurfaces, with horrific consequences. As the court divides, George openly accuses Elizabeth of witchcraft and Edward of murder. This is treason, and Edward must condemn his own brother to death. Elizabeth finally has revenge on those who killed her father, but it does not bring her comfort.

After years of peace an untimely death once again engulfs Elizabeth in a fight for the throne. Trapped in sanctuary and threatened by those closest to her, Elizabeth is forced into an alliance with Margaret Beaufort. Suspicion and doubt poison the court, turning friends into enemies and family into murderers.

The future of the princes in the Tower is in Richard's hands: they are a threat to his reign but also to Margaret's hopes of seeing her son Henry Tudor on the throne. As Margaret plots the boys' removal, Anne is tormented by fears she has unwittingly sealed the princes' fate. Elizabeth, in sanctuary, is horrified to realise she has made a pact with her enemies and turns to witchcraft to punish the guilty.

Princess Elizabeth's engagement to Henry Tudor threatens to divide court loyalties. Richard knows he can no longer avoid the battle which will decide his fate as king. Margaret does not know whose side her husband will support, and fears for her son. As the final battle for the crown draws near, Elizabeth continues to plot to put her daughter on the throne whatever the outcome.
