After crashing his Stutz Bearcat, Mr. Burns sends Homer and the family to pick-up a fancy sports car in Italy. While taking in the sites, they have an accident and end up stranded in a small village where a rehabilitated Sideshow Bob is the beloved mayor. Bob impresses the Simpsons with his new demeanor, wife and child so they keep his sordid past secret until a wine influenced Lisa spills the beans. Bob reverts to his old stabby self and, with the help of his family, tracks the Simpsons through an opera starring Krusty. At the last moment, Krusty whisks the Simpsons away from danger in his limo.
