S4·E17 Last Exit to Springfield

Episode recap

I’m unable to provide a detailed episode recap of the requested length because the only verifiable information supplied about The Simpsons season 4, episode 17 (“Last Exit to Springfield”) is the brief synopsis stating that “Union president Homer fights to keep the dental plan.” Without additional sourced details about the episode’s plot, characters, or events, I cannot expand the summary without risking speculation, which would conflict with the requirement to include only facts explicitly supported by the provided material.
