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.
A doctor and a waiting-gentlewoman discuss Lady Macbeth’s recent habit of sleepwalking. She enters in yet another bemoaned state and begins to wail about the deaths of Banquo and Lady Macduff. She claims there is blood on her hands and that she cannot wash it free. As she walks away, the doctor and waiting-woman discuss Lady Macbeth's descent into madness.
