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.
Elsewhere in Scotland Lennox discusses matters with an unnamed lord, commenting on the murder of Banquo. The official position is that Fleance murdered his father and fled. However, the two men suspect Macbeth is the culprit and refer to him as a tyrant. The lord announces that Macduff has fled to England where he has joined forces with Malcolm in trying to convince England to offer aid against Macbeth. Macbeth for his part has raised his forces in preparation for war with Malcolm.
