Summary
Macbeth, a brave Scottish general, meets three witches who prophesy he will become Thane of Cawdor and then King of Scotland. Spurred on by his wife, Lady Macbeth, he murders King Duncan and seizes the throne. To secure his position he orders further murders, including that of his friend Banquo, descending into tyranny and paranoia. Haunted by guilt and hallucinations, Macbeth and his wife unravel psychologically as rebellion gathers against him. Lady Macbeth dies, apparently by suicide, and Macbeth is finally killed in battle by Macduff, whose family he had slaughtered. Order is restored when Malcolm, Duncan's son, is crowned king.
Plot
Act I - the prophecy
Plot: Returning victorious from battle, Macbeth and Banquo encounter three witches who hail Macbeth as Thane of Cawdor and future king, and Banquo as father of kings. The first prophecy is immediately confirmed, planting the seed of ambition. Lady Macbeth, reading his letter, resolves to push him towards murdering King Duncan, who is coming to stay at their castle.
Act I-II - the murder of Duncan
Plot: Macbeth wavers, torn between ambition and conscience, but Lady Macbeth shames him into action by questioning his manhood. He murders Duncan in his sleep, and the couple frame the king's drunken guards. Duncan's sons, Malcolm and Donalbain, flee in fear of their own lives, inadvertently casting suspicion on themselves and allowing Macbeth to be crowned king.
Act III - the murder of Banquo
Plot: Now king, Macbeth is tormented by the prophecy that Banquo's descendants will inherit the throne. He hires murderers to kill Banquo and his son Fleance, but Fleance escapes. At a state banquet, Macbeth is driven to distraction by the ghost of Banquo, visible only to him, exposing his guilt before the assembled lords.
Act III-IV - descent into tyranny
Plot: Macbeth becomes an increasingly isolated and paranoid tyrant, ruling through fear. He visits the witches again and receives further prophecies: beware Macduff, no man born of woman can harm him, and he is safe until Birnam Wood comes to Dunsinane. Reassured, he orders the slaughter of Macduff's wife and children after learning Macduff has fled to England.
Act IV - the gathering opposition
Plot: In England, Macduff joins Malcolm, who tests Macduff's loyalty before revealing an army has been raised with English support. Macduff learns of his family's murder and vows revenge, strengthening his resolve to destroy Macbeth.
Act V - collapse and downfall
Plot: Lady Macbeth, consumed by guilt, sleepwalks and obsessively tries to wash imaginary blood from her hands before dying, likely by suicide. The English and rebel Scottish forces advance on Dunsinane, camouflaged with branches from Birnam Wood, fulfilling the prophecy. Macbeth, learning Macduff was 'from his mother's womb untimely ripped' and so not technically born of woman, is killed by him in single combat, and Malcolm is proclaimed king.

Themes
ambition and its corrupting power
How: Shakespeare presents unchecked ambition as a destructive force that overrides conscience and morality; Macbeth's desire for power leads him to murder, tyranny and ultimately self-destruction.
Where: Macbeth's soliloquy admitting he has 'no spur to prick the sides of my intent, but only vainaulting ambition'; the escalating murders of Duncan, Banquo and Macduff's family
guilt and conscience
How: guilt manifests psychologically and physically, through hallucinations, sleeplessness and madness, suggesting that moral transgression cannot be escaped even when undetected.
Where: Macbeth's vision of the floating dagger and Banquo's ghost; Lady Macbeth's sleepwalking scene and obsessive hand-washing
fate versus free will
How: the play questions whether Macbeth's downfall is predetermined by the witches' prophecies or caused by his own choices, suggesting the prophecies only succeed because Macbeth chooses to act on them.
Where: the witches' initial prophecies; Macbeth's active decision to murder rather than 'let chance crown me'
kingship and order
How: Shakespeare, writing for King James I, presents legitimate kingship as divinely sanctioned and usurpation as a crime against nature itself, shown through disorder in the natural world following Duncan's murder.
Where: the unnatural storms and strange events on the night of Duncan's murder; Malcolm's restoration of order at the play's end
gender and masculinity
How: the play interrogates conventional ideas of masculinity and femininity, with Lady Macbeth rejecting feminine 'weakness' to enable violence, while Macbeth equates manhood with ruthlessness.
Where: Lady Macbeth's invocation to spirits to 'unsex me here'; her taunting of Macbeth's manhood before Duncan's murder
Places
Macbeth's castles (Inverness and Dunsinane)
What it is: the Macbeths' residences, setting for Duncan's murder and later Macbeth's final stand
Meaning: represents the corruption of domestic and royal order - a place of hospitality turned into a site of betrayal and murder
The heath
What it is: a wild, desolate place outside normal society where the witches appear
Meaning: symbolises chaos, the supernatural and the breakdown of natural order that will spread into the human world
England
What it is: the court of King Edward, where Malcolm has taken refuge
Meaning: represents legitimate, divinely-sanctioned kingship and moral order, in contrast to Scotland under Macbeth's tyranny
Birnam Wood and Dunsinane
What it is: a forest and the hill where Macbeth's castle stands
Meaning: the fulfilment of the witches' seemingly impossible prophecy that Birnam Wood would come to Dunsinane symbolises the inevitability of fate and the folly of over-literal trust in prophecy
