Chiara e Serafina
Don Fernando plots to marry his ward Serafina and enlists pirate Picaro to disrupt her marriage to Don Ramiro. Picaro impersonates Serafina’s long-lost father, while the real father and her sister Chiara arrive in disguise. Pirates later storm the castle; Picaro frees the captives, the sisters reunite, and Serafina and Ramiro affirm their love.
