The Grapes of Wrath

Principal Skinner sends Bart to France because the cherry bomb explosion injures his mother Agnes Skinner. Enraged by Bart's prank that sent his mother flying from the adjacent restroom, Skinner devises what he believes is an excessive punishment by enrolling Bart in a student exchange program to France for three months, initially presenting it as a harsh consequence.

Bart suddenly begins speaking fluent French when he visits a town police officer to report his predicament. After frustration builds due to the language barrier, he experiences a miraculous transformation where he can speak French fluently, allowing him to explain the winemakers' scheme to sell contaminated wine and secure help.

Marge assigns Bart the task of cleaning his room as revenge for his antics, taking advantage of Homer being confined to bed rest after falling down the stairs. With Homer unable to intervene, Marge seizes the opportunity to punish Bart for his mischief.

Bart's life at Château Maison is a harsh contrast to the luxury he anticipated. He is forced into grueling labor by winemakers César and Ugolín, spending his days hauling water buckets, harvesting grapes, and stomping them barefoot. He is deprived of adequate food and freedom, making his experience resembleindentured servitude rather than a student exchange.

Adil Hoxha appears to be a friendly exchange student from Albania who charmed the Simpson family, but his true intent is espionage. He hides a fax machine in Bart's treehouse that transmits sensitive designs back to Albania. The FBI eventually uncovers his secret activities, leading to his deportation as part of a prisoner swap.

While cleaning his room as punishment, Bart discovers an old cherry bomb and, with his characteristic mischief, decides to flush it down the school toilet without considering the consequences. He is unaware that Principal Skinner's mother Agnes is in the adjacent girls' restroom, making the timing particularly disastrous.

After gaining the ability to speak French, Bart reports the winemakers César and Ugolín to the authorities, exposing their scheme to sell contaminated wine. The authorities act quickly, arresting the winemakers, and Bart is celebrated as a hero for unmasking their illicit practices.

Bart returns home to Springfield with vibrant souvenirs, excited to share his experiences. However, his excitement is dampened when Homer mistakenly believes Bart became fluent in French. The truth is revealed that Bart's only French achievement was calling his father the insult 'buffoon' in French.

Homer takes Adil around the nuclear power plant as a way to bond with the exchange student, eager to show him his workplace. Homer is completely unaware of Adil's ulterior motives and covert agenda involving espionage activities hidden from the family.

Bart faces a significant language barrier when he tries to seek help from a police officer in town. The officer has no understanding of English, leaving Bart feeling frustrated and powerless in his dire situation until his miraculous French-speaking ability emerges.

Although hesitant at first about being sent away, Bart is ultimately lured by the promise of residing in a "lovely French château," imagining a dream escape from Springfield. This glamorous depiction convinces him to accept the exchange program assignment.

After the FBI discovers Adil's espionage activities, he is immediately deported to Albania as part of a tense prisoner swap. In exchange, an American spy who was previously held in Albanian detention is freed, though the specific reasons for his captivity remain unclear.
