- Walter and Laura's married life is going well.
- Walter gears up for a showdown with Count Fosco.
- He lets us in on a growing suspicion of his: Fosco is really a foreign spy.
- Walter enlists the help of another Italian to help him identify Fosco: his good friend Pesca.
- Since all Italians must know each other or something? Okay, so Walter thought Pesca was involved in some politics back in Italy and might know Fosco due to his possible involvement in politics.
- Walter follows Fosco around town and sees him buy opera tickets.
- Walter picks up some for himself as well, and Pesca and everyone goes to a night at the opera. (Though probably not in a fun, Marx Brothers way).
