Scotland; some time in the near future. The United Kingdom has splintered, and democracy has given way to authoritarian dynasty rule in the independent nation. National dress has become widely embraced, and border conflicts with England are once again commonplace.
ACT I
As they return victorious from the battlefield, Scottish generals Macbeth and Banquo meet three witches who prophesy the future. They address Macbeth as Thane of Cawdor and King of Scotland, and tell Banquo that he will be the father of kings. The two men try to learn more, but the witches vanish. Messengers arrive with news that Duncan, the current king of Scotland, has made Macbeth Thane of Cawdor. The first part of the witches’ prediction has come true.
In Macbeth’s castle, Lady Macbeth reads a letter from her husband telling her of the events that have just transpired. She resolves to follow her ambitions, and calls on demonic spirits to remove her maternal instincts. A servant announces that Duncan will soon arrive at the castle, and when Macbeth enters, she tells him that they must kill the king. Duncan arrives with the returning war heroes: his son Malcolm, Banquo and Macduff, leading to a series of happy family reunions. Macbeth has a vision of a dagger, then leaves to commit the murder. On his return, he tells his wife how the act has frightened him, and she tells him that he needs more courage; she returns to the site of the murder to smear blood on the King's sleeping attendants.
Banquo enters with Macduff, who discovers the murder, and tries to shield his wife and children from the awful sight. Macbeth and Lady Macbeth pretend to be horrified and join the others in condemning the murder, before Macbeth accuses and executes the King's attendants.
ACT II
Macbeth has become king. Malcolm has fled to England, stoking suspicion that he may have been behind the plot to kill his father. Worried about the prophecy that Banquo’s children will rule, Macbeth and his wife now plan to kill him and his son, Fleance, as well. As Macbeth leaves to prepare the double murder, Lady Macbeth hopes that it will finally make the throne secure.
Outside the castle, assassins wait for Banquo, who appears with his son, warning him of strange forebodings. Banquo is killed, but Fleance escapes.
Lady Macbeth welcomes dignitaries to an unveiling ceremony, and sings a drinking song, while Macbeth receives news that Banquo is dead and his son has escaped. About to take Banquo’s seat, Macbeth has a terrifying vision of the dead man accusing him. His wife is unable to calm her unsettled husband, and the guests wonder about the king’s strange behavior. Macduff fears for his life and vows to escape to England, leaving his wife and children alone in Scotland.
ACT III
The witches gather in greater numbers, and Macbeth visits them, demanding more prophecies. Apparitions warn him to beware of Macduff and assure him that “no man of woman born” can harm him, and that he will be invincible until Birnam Wood marches on his castle. In another vision, he sees a procession of future kings, followed by Banquo. Horrified, Macbeth collapses. The witches disappear and his wife finds him. They resolve to kill Macduff, Lady Macduff and their children.
ACT IV
On the Scottish border, Macduff has joined the refugees. His wife and children have been killed. Malcolm appears with English troops and leads them to invade Scotland.
Lady Macbeth is sleepwalking, haunted by visions of those she and her husband have murdered.
Macbeth awaits the arrival of his enemies and realizes that he will never live to a peaceful old age. Messengers bring news that Lady Macbeth has killed herself, and that Birnam Wood appears to be moving. English soldiers appear, camouflaged with its branches. Macduff confronts Macbeth and tells him that he was not born naturally but had a Caesarean birth. He kills Macbeth and proclaims Malcolm king of Scotland.
