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.
Duncan hears the news of the Thane of Cawdor’s execution, of how he repented his crimes and died a noble death. When Macbeth and Banquo finally return, Duncan greets them as heroes and declares to Macbeth the reward for his deeds. He also announces that his son Malcolm shall be made heir to the throne, to which Macbeth notes that only Malcolm is in his way of the throne now. Plans are made for Duncan to dine at Macbeth’s castle that night and goes ahead of everyone to inform his wife of the impending arrival of the king and what has transpired that day.
