Title: Before Midnight Movie plot: Nine years have passed since Before Sunset. Jesse and Celine have become a couple and parents to twin girls.

After Hank spends the summer with Jesse and Celine on the Greek Peloponnese peninsula, Jesse drops him off at the airport to fly home. Jesse is a successful novelist, while Celine is at a career crossroads, considering a job with the French government. The couple discuss their concerns about Hank, and then about Celine's choices for her career. Over dinner they talk more about love and life. Friends staying with them pay for a hotel room so they can have a night alone. While walking to the hotel, the couple reminisce about coming together. After reaching the hotel, they have a fierce argument, expressing fears about their present and future together. Among other issues, Jesse wants them to move to Chicago so he can be closer to Hank, which Celine thinks will cost her any chance of a life outside her family. In the heat of the argument, Celine tells Jesse she no longer loves him. Celine leaves their room and sits alone in the hotel's outdoor restaurant. Jesse joins her and jokes that he is a time traveler bringing her a letter from her 82-year-old self, describing this night as one of the best of their lives. Unamused, Celine says their fantasies will never match the imperfect reality. Jesse proclaims his love, saying he does not know what else she could want. After a moment, Celine joins in Jesse's joke, and the two seem to reconcile.
