Place: Seville, Spain, and surrounding hills
Time: Around 1820
Act 1
A square, in Seville. On the right, a door to the tobacco factory. At the back, a bridge. On the left, a guardhouse.
A group of soldiers relaxes in the square, waiting for the changing of the guard and commenting on the passers-by ("Sur la place, chacun passe"). Micaëla appears, seeking José. Moralès tells her that "José is not yet on duty" and invites her to wait with them. She declines, saying she will return later. José arrives with the new guard, who is greeted and imitated by a crowd of urchins ("Avec la garde montante").
As the factory bell rings, the cigarette girls emerge and exchange banter with young men in the crowd ("La cloche a sonné"). Carmen enters and sings her provocative habanera on the untameable nature of love ("L'amour est un oiseau rebelle"). The men plead with her to choose a lover, and after some teasing she throws a flower to Don José, who thus far has been ignoring her but is now annoyed by her insolence.
As the women go back to the factory, Micaëla returns and gives José a letter and a kiss from his mother ("Parle-moi de ma mère!"). He reads that his mother wants him to return home and marry Micaëla, who retreats in shy embarrassment on learning this. Just as José declares that he is ready to heed his mother's wishes, the women stream from the factory in great agitation. Zuniga, the officer of the guard, learns that Carmen has attacked a woman with a knife. When challenged, Carmen answers with mocking defiance ("Tra la la... Coupe-moi, brûle-moi"); Zuniga orders José to tie her hands while he prepares the prison warrant. Left alone with José, Carmen beguiles him with a seguidilla, in which she sings of a night of dancing and passion with her lover—whoever that may be—in Lillas Pastia's tavern. Confused yet mesmerised, José agrees to free her hands; as she is led away she pushes her escort to the ground and runs off laughing. José is arrested for dereliction of duty.
Act 2
Lillas Pastia's Inn
Two months have passed. Carmen and her friends Frasquita and Mercédès are entertaining Zuniga and other officers ("Les tringles des sistres tintaient") in Pastia's inn. Carmen is delighted to learn of José's release from two months' detention. Outside, a chorus and procession announces the arrival of the toreador Escamillo ("Vivat, vivat le Toréro"). Invited inside, he introduces himself with the "Toreador Song" ("Votre toast, je peux vous le rendre") and sets his sights on Carmen, who brushes him aside. Lillas Pastia hustles the crowds and the soldiers away.
When only Carmen, Frasquita and Mercédès remain, smugglers Dancaïre and Remendado arrive and reveal their plans to dispose of some recently acquired contraband ("Nous avons en tête une affaire"). Frasquita and Mercédès are keen to help them, but Carmen refuses, since she wishes to wait for José. After the smugglers leave, José arrives. Carmen treats him to a private exotic dance ("Je vais danser en votre honneur ... La la la"), but her song is joined by a distant bugle call from the barracks. When José says he must return to duty, she mocks him, and he answers by showing her the flower that she threw to him in the square ("La fleur que tu m'avais jetée"). Unconvinced, Carmen demands he show his love by leaving with her. José refuses to desert, but as he prepares to depart, Zuniga enters looking for Carmen. He and José fight, and are separated by the returning smugglers, who restrain Zuniga. Having attacked a superior officer, José now has no choice but to join Carmen and the smugglers ("Suis-nous à travers la campagne").
Act 3
A wild spot in the mountains
Carmen and José enter with the smugglers and their booty ("Écoute, écoute, compagnons"); Carmen has now become bored with José and tells him scornfully that he should go back to his mother. Frasquita and Mercédès amuse themselves by reading their fortunes from the cards; Carmen joins them and finds that the cards are foretelling her death, and José's. The women depart to suborn the customs officers who are watching the locality. José is placed on guard duty.
Micaëla enters with a guide, seeking José and determined to rescue him from Carmen ("Je dis que rien ne m'épouvante"). On hearing a gunshot she hides in fear; it is José, who has fired at an intruder who proves to be Escamillo. José's pleasure at meeting the bullfighter turns to anger when Escamillo declares his infatuation with Carmen. The pair fight ("Je suis Escamillo, toréro de Grenade"), but are interrupted by the returning smugglers and girls ("Holà, holà José"). As Escamillo leaves he invites everyone to his next bullfight in Seville. Micaëla is discovered; at first, José will not leave with her despite Carmen's mockery, but he agrees to go when told that his mother is dying. As he departs, vowing he will return, Escamillo is heard in the distance, singing the toreador's song.
Act 4
A square in Seville. At the back, the walls of an ancient amphitheatre
Zuniga, Frasquita and Mercédès are among the crowd awaiting the arrival of the bullfighters ("Les voici ! Voici la quadrille!"). Escamillo enters with Carmen, and they express their mutual love ("Si tu m'aimes, Carmen"). As Escamillo goes into the arena, Frasquita and Mercedes warn Carmen that José is nearby, but Carmen is unafraid and willing to speak to him. Alone, she is confronted by the desperate José ("C'est toi ! C'est moi !"). While he pleads vainly for her to return to him, cheers are heard from the arena. As José makes his last entreaty, Carmen contemptuously throws down the ring he gave her and attempts to enter the arena. He then stabs her, and as Escamillo is acclaimed by the crowds, Carmen dies. José kneels and sings "Ah! Carmen! ma Carmen adorée!"; as the crowd exits the arena, José confesses to killing the woman he loved.

Act 1
Scene 1
A group of Cenobite monks go about their daily business. Athanaël, the most rigorous ascetic of them all, enters and confesses to the senior monk, Palémon, that he has lately been disturbed by visions of a courtesan and priestess of Venus named Thaïs, whom he had seen many years ago in his native city of Alexandria. Believing these visions to be a sign from God, he resolves, against Palémon's advice, to return to Alexandria, convert Thaïs to Christianity, and persuade her to enter a convent.
Scene 2
Athanaël arrives in Alexandria and visits his old friend Nicias, a wealthy voluptuary. Nicias welcomes him with open arms and reveals himself to be Thaïs's current lover. Upon hearing Athanaël's plan, he laughs and warns him that the revenge of Venus can be terrible. Nevertheless, he procures clothing for his friend in preparation for a feast that evening at which Thaïs will appear. His slaves, Crobyle and Myrtale, dress Athanaël and mock his prudery.
The feast begins. Thaïs arrives and sings a bittersweet love duet with Nicias: this is their last night together. She then asks him about Athanaël, who overhears her and tells her that he has come to teach her "contempt for the flesh and love of pain." Not tempted by this proposition, she offends his sense of propriety with a seductive song. He leaves, angrily promising to come back later, while she taunts him with a parting shot: "Dare to come, you who defy Venus!" and begins to disrobe as the curtain falls.
Act 2
Scene 1
Exhausted after the feast, Thaïs expresses dissatisfaction with her empty life and muses on the fact that one day, old age will destroy her beauty. Athanaël enters at this vulnerable moment, praying to God to conceal her beauty from him. He tells her that he loves her according to the spirit rather than the flesh, and that his love will last forever instead of a single night. Intrigued, she asks him to teach her the ways of this love. He nearly succumbs to her physical charm, but succeeds in explaining to her that if she converts, she will gain eternal life. She nearly succumbs to his eloquence, but then reasserts her nihilistic worldview and drives him away. However, after a long meditation she changes her mind.
Scene 2
Thaïs has joined Athanaël and resolved to follow him into the desert. He orders her to burn down her house and possessions in order to destroy all traces of her wicked past. She agrees, but asks if she can keep a statuette of Eros, the god of love, explaining to Athanaël that she sinned against love rather than through it. When he hears that Nicias gave it to her, however, Athanaël demands that she destroy it. Nicias appears with a group of revelers, who see Athanaël taking Thaïs away. Furious, they begin to stone him. Although Nicias is astonished at Thaïs' decision to leave, he respects it and throws handfuls of money to distract the crowd. Thaïs and Athanaël escape.
Act 3
Scene 1
Thaïs and Athanaël travel on foot through the desert. Thaïs is exhausted, but Athanaël forces her to keep going and thus do penance for her sins. They reach a spring, where Athanaël begins to feel pity rather than disgust for her, and they share a few moments of idyllic, platonic companionship as they rest. Shortly afterwards, they reach the convent where Thaïs is to stay. Placing her in the care of Mother Superior Albine, Athanaël realizes that he has accomplished his mission — and that he will never see her again.
Scene 2
The Cenobite monks express anxiety over Athanaël's asocial and morose behavior since his return from Alexandria. Athanaël enters and confesses to Palémon that he has begun to experience sexual longing for Thaïs. Palémon castigates him for having attempted to convert her in the first place. Athanaël falls into a depressed sleep and has an erotic vision of Thaïs. He tries to seize her, but she laughingly evades him. Then, a second vision tells him that Thaïs is dying.
Scene 3
Feeling that existence is worth nothing without her, he repudiates all his vows and rushes off to find her. He reaches the convent and finds her on her deathbed. He tells her that all he taught her was a lie, that "nothing is true but life and the love of human beings", and that he loves her. Blissfully unaware, she describes the heavens opening and the angels welcoming her into their midst. She dies, and Athanaël collapses in despair.

Time:1849 to 1850
Place: A mining camp at the foot of the Cloudy Mountains, California
Act 1
Inside the Polka Saloon
A group of Gold Rush miners enter the "Polka" saloon after a day working at the mine ("Hello! Hello! Alla 'Polka'"). After a song by traveling minstrel Jake Wallace ("Che faranno i vecchi miei"), one of the miners, Jim Larkens, is homesick and the miners collect enough money for his fare home ("Jim, perchè piangi?").
A group of miners playing cards discover that Sid is cheating and want to attack him. Sheriff Jack Rance quiets the fight and pins two cards to Sid's jacket, as a sign of a cheat.
A Wells Fargo agent, Ashby, enters and announces that he is chasing the bandit Ramerrez and his gang of Mexicans. Rance toasts Minnie, the woman who owns the saloon, as his future wife, which makes Sonora jealous. The two men begin to fight. Rance draws his revolver but at that moment, a shot rings out and Minnie stands next to the bar with a rifle in her hands ("Hello, Minnie!"). She gives the miners a reading lesson from the Bible ("Dove eravamo?").
The Pony Express rider arrives ("La posta!") and delivers a telegram from Nina Micheltorena, offering to reveal Ramerrez's hideout. The sheriff tells Minnie that he loves her, but Minnie puts him off as she is waiting for the right man ("Ti voglio bene, Minnie").
A stranger enters the saloon and asks for a whisky and water. He introduces himself as Dick Johnson from Sacramento, whom Minnie had met earlier. Johnson invites Minnie to dance with him and she accepts. Angrily, Rance watches them.
Ashby returns with the captured Ramerrez gang member, Castro. Upon seeing his leader, Johnson, in the saloon, Castro agrees to lead Rance, Ashby and the miners in a search for Ramerrez, and the group then follows him on a false trail and in what turns out to be a wild goose chase. But before Castro leaves, he whispers to Johnson that somebody will whistle and Johnson must reply to confirm that the place is clear. A whistle is heard, but Johnson fails to reply.
Minnie shows Johnson the keg of gold that she and the miners take turns to guard at night and Johnson reassures her that the gold will be safe there. Before he leaves the saloon, he promises to visit her at her cabin. They confess their love for each other. Minnie begins to cry, and Johnson comforts her before he leaves.
Act 2
Minnie's dwelling, later that evening
Wowkle, a Native American woman who is Minnie's servant, her lover Billy Jackrabbit and their baby are present as Minnie enters, wanting to get ready for Johnson's visit. Johnson enters Minnie's cabin and she tells him all about her life. It begins to snow. They kiss and Minnie asks him to stay till morning. He denies knowing Nina Micheltorena. As Johnson hides, a posse enters looking for Ramerrez and reveal to Minnie that Johnson is the bandit Ramerrez himself. Angry, she orders Johnson to leave. After he leaves, Minnie hears a gunshot and she knows Johnson has been shot. Johnson staggers in and collapses, Minnie helps him by hiding him up in the loft. Rance enters Minnie's cabin looking for the bandit and is about to give up searching for Johnson when drops of blood fall on his hand. Rance forces Johnson to climb down. Minnie desperately makes Rance an offer: if she beats him at poker, he must let Johnson go free; if Rance wins, she will marry him. Hiding some cards in her stockings, Minnie cheats and wins. Rance honors the deal and Minnie throws herself on the unconscious Johnson on the floor.
Act 3
In the Great Californian Forest at dawn, sometime later
Johnson is again on the run from Ashby and the miners. Nick and Rance are discussing Johnson and wonder what Minnie sees in him when Ashby arrives in triumph: Johnson has been captured. Rance and the miners all want Johnson to be hanged. Johnson accepts the sentence and only asks the miners not to tell Minnie about his capture and his fate ("Ch'ella mi creda"). Minnie arrives, armed with a pistol, just before the execution and throws herself in front of Johnson to protect him. While Rance tries to proceed, she convinces the miners that they owe her too much to kill the man she loves, and asks them to forgive him ("Ah! Ah! E Minnie!"). One by one, the miners yield to her plea ("E anche tu lo vorrai, Joe"). Rance is not happy but finally he too gives in. Sonora unties Johnson and sets him free. The miners bid Minnie farewell ("Le tue parole sono di Dio"). Minnie and Johnson leave California to start a new life together.
