When a baby, the King of Barataria's son was stolen and apparently raised by a Venetian gondolier, and the daughter of the Spanish Duke of Plaza Toro promised his daughter Casilda (also when she was a baby) to him in marriage. It appears that the king is either Marco or Giuseppe Palmieri. Problem is, Marco and Giuseppe have already married other girls and the Duke's servant, Luiz is in love with Casilda.
