A brave man named Macbeth receives a prophecy from a trio of witness that one day he will become king of Scotland. Consumed by ambition and spurred to action by his wife, Macbeth murders king Duncan and takes the Scottish throne for himself.
Three witches gather and say that they will meet with Macbeth before sunset and after a terrible battle that has been fought nearby. The witches are later referred to as the "Three weird sisters." The scene is set on a battlefield where Macbeth's army has been fighting the army of the traitor Macdonwald.
The sergeant says that the battle was evenly matched with the "whore" fortune smiling temporarily on Macdonwald until Macbeth banished his steel which smoked bloody execution. Macbeth carved his way through Macdonwald's men until he came face to face with his slave. Macdonwalds men run, the king of Norway fights on the side of Macdonwald.
At this point, Norway sends his fresh forces to onto the field to fight Macbeth and Banquo's tired and battle worn men. Macbeth's men defeat Norway's army and then march to fife, where Norway- here working with the traitor the throne of Cawdor has a second force of battling the loyal Scottish thane.
Macbeth and Banquo ride from the battlefield. Macduff confronts Macbeth. Seward ironically observes that they have been very successful with no deaths. Malcolm immediately assumes his rightful place of king.
