Macbeth is a Shakespearian tragedy about Macbeth, a nobleman and renowned warrior. After witches inform him that he will be king, he travels with his companion Banquo to King Duncan's castle. Macbeth's wife, Lady Macbeth, convinces him to kill Duncan and he obeys. After killing Banquo and others, Banquo's ghost returns to the castle, haunting Macbeth. Macbeth receives a tragic prophesy from the witches, Lady Macbeth kills herself out of guilt and King Duncan's son, Prince Malcom, invades the kingdom and kills Macbeth.
Beyond the castle gates, the Scottish lords are discussing the approaching English forces. The Scottish forces themselves will meet up with Malcolm and Macduff at the Birnam Wood. Macbeth, the tyrant as they refer to him, has gone into a rage, fortifying the castle at Dunsinane.
