SYNOPSIS
ACT I
Friends and courtiers of Gustavus III await him in the throne room of the palace, among them a group of conspirators led by Counts Horn and Ribbing. As the king enters, his page, Oscar, gives him the guest list for a masked ball. Seeing the name of Amelia - wife of his first minister, Anckarstrøm - he muses on his secret passion for her (La rivedrà nell'estasi). As the others leave, the page admits Anckarstrøm himself, who says he knows the cause of the king's disturbed look: a conspiracy against the crown. But Gustavus ignores his friend's warning.
A magistrate arrives with a decree banishing the fortune teller Mlle Arvidson, who has been accused of witchcraft. When Gustavus asks Oscar's opinion, the youth describes her skill at stargazing and urges him to absolve her of any crime (Volta la terrea). Deciding to see for himself, and overruling the objections of Anckarstrøm, the king light-heartedly bids the court join him in an incognito visit to the soothsayer.
As Arvidson mutters incantations before a group of women (Re dell'abisso), Gustavus discreetly enters disguised as a fisherman. The fortune teller begins her prophecies by telling the sailor Cristian that he will soon prosper. Gustavus surreptitiously slips money and a promotion into the satchel of the seaman, who discovers it and marvels at the fortune teller's powers. The king stays in hiding when Arvidson sends her visitors away to grant an audience to Amelia, who comes seeking release from her love for Gustavus. Arvidson tells her she must gather at night a magic herb that grows by the gallows. Amelia hurries away as Gustavus, having overheard the conversation, resolves to follow her. A moment later Oscar and members of the court enter, and Gustavus, still disguised as a fisherman, mockingly asks Arvidson to read his palm (Di' tu se fedele). When she says he will die by the hand of a friend, the king laughs (Quintet: È scherzo od è follia). Still incredulous, Gustavus asks her to identify the assassin, to which she replies that the next hand he shakes is the one that will kill him. No one will shake the fisherman's hand, but upon seeing Anckarstrøm arrive, he hurries to clasp his hand and says that the oracle is now disproved, since Anckarstrøm is his most loyal friend. Gustavus is recognized, and is hailed by the crowd above the muttered discontent of the conspirators.
ACT II
Amelia arrives by the gallows and desperately prays that the herb she seeks will release her from her passion for the king (Ma dall'arido stelo divulsa). As a distant bell tolls midnight, she is terrified by an apparition and prays to heaven for mercy. Gustavus arrives, and unable to resist his ardent words, Amelia confesses she loves him (Duet: Non sai tu che se l'anima mia) but quickly veils her face when her husband rushes in to warn the king to flee approaching assassins.
Gustavus, fearing that Anckarstrøm may discover Amelia's identity, leaves only after the Captain promises to escort her back to the city without lifting her veil. Finding Anckarstrøm instead of their intended victim, the conspirators curse their luck. The husband draws his sword when they make insolent remarks about his veiled companion. To save her husband's life, Amelia raises her veil. While the conspirators laugh at this irony, Anckarstrøm asks their two leaders to come to his house the next morning and Amelia laments her disgrace.
ACT III
Dragging Amelia into their home, Anckarstrøm tells her that he intends to kill her. Amelia asks to see her young son before she dies (Morrò, ma prima in grazia). Granting her wish, Anckarstrøm turns to a portrait of Gustavus and exclaims that it is not on Amelia that he should seek vengeance, but on the king (Eri tu). He is interrupted by Horn and Ribbing. Now united in purpose, they cannot agree who should have the privilege of assassinating the king. Amelia returns just as the men prepare to draw lots. Forcing his wife to choose the fatal slip of paper from a vase, Anckarstrøm rejoices when she draws his name. A moment later Oscar brings an invitation to a masked ball at the opera house. While the men hail this chance to execute their plan, Amelia plans to warn Gustavus (Quintet: Di che fulgor).
Alone in his apartment, Gustavus resolves to renounce his love, and to send Amelia and Anckarstrøm to Finland (Ma se m'è forza perdeti). Oscar delivers a letter to the king from an unknown lady warning him of the murder plot. Not wanting his absence to be taken as a sign of cowardice, Gustavus leaves for the masquerade.
In the Royal Opera House ballroom, festivities are in progress. The three conspirators wander through the crowd trying to learn the disguise of the king. Anckarstrøm, taking Oscar aside, tries to persuade the youth to reveal the king's identity and is successful only after the boy's playful evasions (Saper vorreste). Recognizing Amelia, Gustavus speaks with her (Duet: T'amo, sì, t'amo). Despite her repeated warning, he refuses to leave. Just as the lovers bid a final farewell, Anckarstrøm, overhearing the last part of their conversation, plunges his dagger into the king. The dying Gustavus forgives Anckarstrøm, and admits he loved Amelia but assures the remorseful captain of his wife's innocence. The crowd bewails the loss of such a generous-hearted king.
