La Tosca plot
Cesare Angelotti, a former consul, is sentenced to death for participating in a conspiracy against the tyranny that rules the country. He is further helped by his friend Mario Cavaradossi, a young painter. A little later, the police officer Scarpia reaches the church. He notes the resemblance between the portrait of Mary Magdalene, which Cavaradossi worked on, and the countess from Rome named Attavanti. Scarpia shows these details to Cavaradossi's beloved singer Tosca, which makes her jealous. Tosca goes to Cavaradossi's house with Scarpia's men. Believing that he will find the prisoner there, the chief of police seduces Tosca, with whom he has long been in love.
