The film does not follow a traditional linear plot with a twist, but its structural 'spoiler' is the confirmation of the opening monologue: Alvy and Annie do not get back together. After a breakup, Alvy flies to Los Angeles to propose to Annie, who is now living with Tony Lacey. She rejects his proposal, choosing her new independent life.
Alvy returns to New York and writes a play about their relationship, but in the play, he changes the ending so that she accepts him. This reveals Alvy's inability to accept reality. The film ends with a chance encounter years later; they chat briefly as friends and then part ways. The final montage of their happy moments serves as a bittersweet eulogy to the relationship, reinforcing the theme that the value of love lies in the experience, not the permanence.
