The Barber of Seville
Count Almaviva, in disguise as the poor student Lindoro, falls in love with Rosina, who is confined by her guardian Bartolo. With Figaro’s help, Almaviva repeatedly disguises himself to enter Bartolo’s house and reach Rosina. After Bartolo convinces Rosina that Lindoro has betrayed her, she agrees to marry Bartolo; Almaviva reveals his identity, and the pair marry before Bartolo can stop them.
