After being humiliated by Mrs. Krabappel's class, Mr. Burns finally decides to buy a new car, so he orders a Lamborgotti Fasterossa. He sends Homer and his family to the factory in Italy to pick the car up. The family takes a tour of Italy in the new car, but an accident with the car and a cheese truck has the family pushing the car into the town of Salsiccia. They find out that only one person in the town speaks English and it happens to be their mayor. The family goes to meet the mayor and they are surprised to see that it is Sideshow Bob, and he is equally surprised to see them. Sideshow Bob tells them how he came to Italy, become mayor and started a family with his wife (Francesca) and son (Gino). He hopes that the Simpsons will keep the secret of his criminal past, but Lisa’s first exposure to drinking wine leads to loose lips, which sinks his ship. Sideshow Bob, being no longer welcome in his new home, swears a vendetta on the Simpson family. The Simpsons go on the run from Sideshow Bob, who is joined by his wife and son as the vendetta affects their entire family. In Rome, the family discovers that Krusty is preparing to perform the lead in “I Pagliacci.” The Simpsons hide as extras within the show, but Krusty gets tossed off-stage only to be replaced by Sideshow Bob, whose family has the Simpsons surrounded. Krusty and his limo save the day, while Sideshow Bob and his family adjust to their unresolved vendetta.
