What Is the Plot of Hamlet? Act-by-Act Summary
The plot of Hamlet follows a Danish prince whose father’s ghost accuses his uncle Claudius of murder. Hamlet investigates and seeks revenge, but his killing of Polonius sets off further tragedy. Claudius plots Hamlet’s death through a poisoned duel, which kills Hamlet, Laertes and Gertrude. Hamlet kills Claudius before dying.
What is the plot of Hamlet?
Act 1 establishes a revenge plot inside a troubled royal family. Prince Hamlet is mourning his father, the former king of Denmark. His uncle Claudius has become king and married Hamlet’s mother, Gertrude. Hamlet is distressed by both the death and the swift marriage.
After guards and Hamlet’s friend Horatio see a ghost resembling the dead king, Hamlet joins their watch. The Ghost speaks privately to him: Claudius murdered him by pouring poison into his ear while he slept. It orders Hamlet to avenge the murder, but to leave Gertrude to heaven and her conscience (Act 1, Scene 5).
Hamlet agrees to pursue revenge and warns his companions that he may adopt an ‘antic disposition’ — behave as though he is mad (Act 1, Scene 5). This establishes an important uncertainty: other characters will struggle to distinguish his performance from genuine distress.
Meanwhile, Ophelia’s father Polonius orders her to stop seeing Hamlet. Before the revenge begins, the court is already a place where family authority restricts private relationships.
Act 2: Hamlet plans to test Claudius
Hamlet’s strange behaviour attracts attention. Ophelia reports a disturbing visit from him, and Polonius concludes that frustrated love has made him mad. Claudius and Gertrude recruit Hamlet’s old friends Rosencrantz and Guildenstern to discover what troubles him. Hamlet soon recognises that they have been sent for.
The arrival of travelling actors gives him another way to investigate his father’s death. He asks them to perform a play resembling the murder described by the Ghost, hoping that Claudius’s reaction will reveal his guilt.
Hamlet explains his plan through the phrase ‘catch the conscience of the king’ (Act 2, Scene 2). The performance will be a test, not merely entertainment.
This matters because Hamlet does not yet regard the Ghost’s accusation as sufficient proof. He worries that the spirit could be a devil exploiting his grief. His delay therefore has a practical and moral purpose: he wants evidence before committing revenge. At the same time, he reproaches himself for speaking and thinking rather than acting.
Act 3: The play exposes Claudius
Claudius and Polonius secretly observe Hamlet’s meeting with Ophelia. Hamlet rejects her, and Claudius concludes that love is not the explanation for his behaviour. He decides to send Hamlet to England.
At the court performance, an actor pours poison into a sleeping ruler’s ear. Claudius abruptly stops the entertainment and leaves. Hamlet and Horatio interpret his response as confirmation of his guilt (Act 3, Scene 2).
The audience then hears Claudius admit his crime in private. When Hamlet finds him apparently praying, he decides not to kill him, fearing that death during prayer would send Claudius to heaven. Ironically, Claudius cannot truly repent because he will not surrender the rewards of his murder (Act 3, Scene 3).
The decisive turning point comes in Gertrude’s chamber. Hearing someone behind a wall hanging, Hamlet stabs through it, killing Polonius, who has been eavesdropping (Act 3, Scene 4). Hamlet’s first major act of violence kills the wrong man. His revenge now creates another family’s demand for vengeance.
Act 4: Revenge spreads to Laertes
After Polonius’s death, Claudius sends Hamlet towards England with Rosencrantz and Guildenstern. They carry a secret order requiring Hamlet’s execution. Claudius is no longer simply watching Hamlet: he is actively trying to have him killed.
On the journey, Hamlet encounters a captain from Fortinbras’s army. The soldiers’ willingness to fight over a small piece of territory makes him condemn his own delay (Act 4, Scene 4).
Back in Denmark, Ophelia suffers a mental breakdown following her father’s death. Her brother Laertes returns angrily, demanding answers. Claudius redirects Laertes’s desire for revenge towards Hamlet.
Letters then announce that Hamlet is returning after an encounter with pirates. Claudius and Laertes arrange a fencing match in which Laertes will use an unblunted, poisoned blade. Claudius prepares poisoned wine as a second method of killing Hamlet (Act 4, Scene 7).
Gertrude brings news that Ophelia has drowned. Laertes now mourns both his father and his sister, making him especially vulnerable to Claudius’s manipulation. The revenge plot has become a chain of retaliations.
Act 5: The graveyard and the poisoned duel
Back in Denmark, Hamlet visits a graveyard with Horatio. Holding the skull of Yorick, the court jester he knew as a child, he confronts the physical reality of death. When Ophelia’s funeral arrives, he learns that she has died and clashes with Laertes at her grave (Act 5, Scene 1).
Hamlet later explains that he discovered Claudius’s execution order and replaced it with one demanding the deaths of Rosencrantz and Guildenstern. He then accepts the fencing match with Laertes.
The final duel turns Claudius’s scheme against everyone involved. Gertrude drinks the poisoned wine intended for Hamlet. Laertes wounds Hamlet with the poisoned blade; after they exchange weapons, Hamlet wounds Laertes. The dying Laertes reveals the plot and identifies Claudius as responsible. Hamlet stabs Claudius and forces him to drink the poison (Act 5, Scene 2).
Hamlet and Laertes exchange forgiveness before dying. Horatio survives to tell the story. Fortinbras arrives, asserts his claim to Denmark and orders military honours for Hamlet. Revenge is completed, but the royal family is destroyed and power passes to a foreign prince.
Questions
Why does Hamlet delay killing Claudius?
Hamlet initially doubts whether the Ghost is trustworthy and seeks evidence through the play. Later, he refuses to kill Claudius while he appears to pray, fearing this would send him to heaven. His delay combines uncertainty, moral and religious concerns, and a desire for revenge that fully punishes his uncle.
Is Hamlet really mad or only pretending?
Hamlet announces that he may put on an ‘antic disposition’ (Act 1, Scene 5), so some of his behaviour is deliberately performed. However, his grief, anger and distress are real. The play does not make every action easy to classify as either calculated pretence or genuine mental disturbance.
Who dies at the end of Hamlet?
In Act 5, Scene 2, Gertrude, Laertes, Claudius and Hamlet die during the poisoned duel and its aftermath. English ambassadors also report that Rosencrantz and Guildenstern have been executed. Polonius and Ophelia die earlier. Horatio survives to explain what happened, while Fortinbras arrives to claim the kingdom.
What is the main conflict in Hamlet?
The central conflict is Hamlet’s attempt to avenge his father’s murder by Claudius. This creates both an outward struggle against a dangerous king and an inward struggle over evidence, duty, death and the morality of revenge. Killing Polonius also makes Hamlet the target of Laertes’s revenge.
