(Note: in the score the tableaux are designated with continuous numbering.)

Tableau 1. The Grinevs' house. The father decides to send his seventeen-year-old son Petr off to become a soldier; the household bids him farewell as he leaves with Savel'ich. An orchestral interlude represents their journey, in which they are trapped in a snowstorm and rescued by a Guide.

Tableau 2. Arriving at an inn, the three of them set up lodgings. The Guide and the Innkeeper converse in coded language. Everyone goes to bed. Petr has a dream in which his father lies dying on a bed with his mother and servants around. Petr walks up to the scene and finds that the man in the bed is not his father, but the Guide, who tries to bless him and then waves an axe in all directions, causing a disturbance. The dream ends as a rooster crows and dawn breaks. The guests prepare for travelling again. Petr gives his coat to the Guide to stay warm. The three leave.

Tableau 3. Belogorsky Fortress, the square and the porch of the Commandant's house. Zharkov is helping Mironova wind her yarn, a group of invalid soldiers marches past. Petr, who has already settled in, reads a love poem he has written to get Shvabrin's opinion. This leads to an argument between them concerning Masha; they agree to a duel and go off elsewhere to take care of it. The invalids march by once more. Savel'ich, who has seen the duel, arouses the residents. Petr is brought in on a stretcher unconscious and taken into the Mironov's house.

Tableau 4. A room in the Commandant's house. Petr lies asleep, still recovering. Masha sings to him. He awakens and proposes marriage to her, but she is concerned about whether his family will accept her; he assures her otherwise. Savel'ich enters with a letter from Grinev which refuses permission to Petr to marry Masha. She cannot marry without Petr's parents' consent and exits. Petr vows to convince his father.

Mironov enters, reading aloud a letter from the General. Pugachev has sacked several fortresses, and must be destroyed. Mironova tells of the capture of another fortress. Mironov decides that Masha should be sent away for safety. Mironova, Zharkov, Petr, Shvabrin, and Mironov join in a patriotic oath not to surrender.

Tableau 5. Belogorsky Fortress (same setting as Tableau 3). Preparations are made in the fortress for an attack. Mironov takes leave of Mironova. The insurgents attack the fortress and take it. Pugachev comes on the scene. Mironov and Zharkov are executed by hanging (offstage). Pugachev recognizes Petr, though, and spares him. Although the people beg him to, Petr will not kiss Pugachev's hand. In runs Mironova, mourning her husband. She is taken away to be killed.

Pugachev welcomes Petr. The men and women dance, and Chumakov strikes up a song. Pugachev and Petr are left alone to converse. It is revealed that Pugachev was the guide to whom Petr gave his coat. However Petr refuses to be a traitor, and goes off. Pugachev is left wondering about his fate as a last string of Chumakov's song is sung.

Tableau 6. A room in the Commandant's house (same setting as Tableau 4). Masha, locked in the room, is now an orphan. Shvabrin enters and begs her to marry him. She refuses, and he exits, but outside the room he runs into Pugachev and Petr. He makes up a story that she is being kept there because she is ill, and that they are married. Masha reveals the truth. Pugachev sets Masha free. Petr, who still cannot give Pugachev his allegiance, nevertheless is grateful to Pugachev. He asks Pugachev to let him and Masha leave. Pugachev agrees, tells Shvabrin to give them a pass to travel, and bids them farewell. Left alone, the two lovers discuss their plans. Petr will take Masha to his parents house, and his father will be honored to have the daughter of brave Captain Mironov in his house.

Tableau 7. The Grinevs' house (same setting as Tableau 1). Masha is now living there, but Petr has been arrested. She explains to the Grinev's that he got into trouble only because he was trying to protect her. She will go to Tsarskoye Selo to try to plead for him among influential people. Petr's parents bless her.

Tableau 8. A hall in the Imperial palace in Saint Petersburg. Courtiers sing the praises of the Empress. She makes her entrance and announces that Pugachev has been captured. Masha and the Grinev family enter. The Empress grants Masha's request by pardoning Petr, and blesses their life together, as the courtiers resume their praise.
