' Macbeth, the king!' they say, but Macbeth is not a king, he is just a simple soldier. Macbeth and Banquo cannot forget the witches' words. Soon Macbeth is king, but his wife walks in her sleep a night, and dreams of blood. What lies in the future for Banquo? And how many people must die before Scotland finds peace once more?
