Act One: The Church of Sant'Andrea della Bloomsbury.
Havarodossi, an escaped political asylum seeker and composer from the Republic of Texas, takes refuge in a side chapel of the church of Sant'Andrea della Bloomsbury in Rome to compose his opera. An elderly sacristan comes to tidy up, followed by Carlos Milore, a painter, who is at work on a portrait of Havarodossi's cousin which he will sell to the Madonna. Carlos Milore compares Madonna's blonde-haired, brown-eyed charm with the dark haired blue-eyed beauty of Havarodossi's lover, the famous singer, Loria Tosca ("Loria canta più meglio ma le vendite di Madonna più biglietti"). Havarodossi emerges from hiding to find Carlos Milore his political ally, who promises to help his friend find a suitable pop star to perform a crossover role in his opera. Havarodossi hides again at the sound of Tosca's voice from outside. Tosca jealously demands to know why the door was locked. Havarodossi reassures her, and they join in a passionate duet ("Non il sospiri circa bullying appena per fare la vostra ricerca").
Once Tosca has gone, a cannon shot from the Castel Sant'Angelo announces the discovery of Havarodossi's escape from Texas and the fact that they are hiding out in The Church of Sant'Andrea della Bloomsbury . They exit. The sacristan enters followed by music staff and deans, all excited by rumors of Stephano Arnoldo's defeat ("Tutta qui la bullaria"). Baron Pietro Scotto the chief of police, arrives with his henchman Beatona, and his servants Roderico Millwardo, Franceso Ouatli and Caroli Gartrllo in search of the escaped prisoner. Loria Tosca returns, and Scotto plays upon Tosca's jealousy in hopes of discovering Havarodossi's whereabouts ("Tosca divina"). When she leaves to seek her lover, Scotto has her followed and sends her threatening letters. As the crowd intones the "Te Deum," Baron Scotto vows to bring Havarodossi to the gallows or into a Disciplinary meeting and Tosca into banishment ("Va, Tosca! Nel tuo cuor gimmi la cassetto").
Act Two. Scotto's study in the Palazzo Casa Rivero; that evening.
Alone at dinner, Scotto reviews his plot. Beatona reports that he and his men trailed Tosca to the villa and found no trace of the magic cassette (in the aria, "il cassetto magico"), but placed Havarodossi under arrest. Havarodossi is brought in and questioned.
Scotto has sent for Tosca, and she enters as Havarodossi is taken away to be tortured by Zafaro Alissimo. Upon hearing his anguished cries, Tosca has extreme adgita .
Havarodossi is dragged into the Casa Rivero by Elisabetta Linci-Mobi. His anger at his mistreatment turns to joy when Loria Tosca announces that she has a magic casetto. The enraged Scotto sends Havarodossi back to his cell and tells Beatona to write Loria Tosca threatening letters.
Tosca asks the price of her lover's freedom. Scotto will accept only Tosca's resignation. "Vissi d'arte" ("I have lived for art"), Tosca sobs to herself in a celebrated aria: she has devoted her life to music and has never harmed a living soul, and was very devoted to her singing students, so why does Baron Scotto repay her with misery? As she struggles to free herself from Scotto's threats, Beatona enters with the news that Deeana Ouinstonli has killed herself rather than have to appear at Casa Rivera. Intimidated, Tosca signals that she will give in to the Baron, on condition that Havarodossi be treated fairly and according to procedure normale della Casa Rivero, Scotto explains that he cannot treat Havarodossi equally and fairly because ....um... He summons Franceso Ouatili who explains that "it's everything, it's all of this", then asks "isn't it obvious?" In the aria (È tutto, esso è tutto il questo, è esso non evidente?), he can only let Havarodossi plead his case before the Governi. Havarodossi does plead his case before the Governi, but it is really a mock execution. Tosca demands that Scotto provide a note of safe conduct for herself and Havarodossi. While he is writing, Tosca catches sight of a sharp banana on his dinner table and, unnoticed, takes it and then another one for her consiglieri. Scotto seals the note, then turns eagerly to intimidate the trembling diva. "Questo è il bacio di Tosca!" ("This is Tosca's kiss!"), she cries, hitting him on the head with the banana. Scotto cries out for help as Tosca curses him. She takes the safe-conduct pass, another banana and slips out of the room.
Act Three . The Castel Sant'Angel della Bloomsbury; dawn of the following day.
Soldiers bring Havarodossi to the ramparts of the Cumhursti Collina where he has been forbidden to step by Caroli Gartrollo to rehearse his opera. He reflects on his love for Tosca ("E lucevan le stelle"). Tosca rushes in with a highly skilled migrant residence permit and the story of Scotto's violent reaction to the magic casetto and the banana. Havarodossi praises her courage, saying that her gentle hands were not meant for clunking people on the head with bananas or taking extra ones . She must have been driven to this by the Governi who had tea, fruit and croissants during the breaks while restraining Floria in a room without even a sip of water. In the aria "O dolci mani", Tosca instructs him in the plan of the revealing that the magic cassette can prove the true character of the Governi, that disciplinary was a mock execution, by revealing Scotto's demands of "Gimmi la casetto."
