At dawn, Cavaradossi awaits execution on the ramparts of Castel Sant’Angelo. He bribes the jailer to deliver a farewell letter to Tosca, and then, overcome with emotion, gives in to his despair. Tosca appears and explains what has happened. The two imagine their future in freedom. As the execution squad arrives, Tosca implores Cavaradossi to fake his death convincingly, then watches from a distance. The soldiers fire and depart. When Cavaradossi doesn’t move, Tosca realizes that the execution was real, and Scarpia has betrayed her. Scarpia’s men rush in to arrest her, but she cries out that she will meet Scarpia before God and leaps from the battlement.
