Set four years after the events of the series finale, the film begins with a montage of Carrie (Sarah Jessica Parker), Samantha (Kim Cattrall), Charlotte (Kristin Davis) and Miranda (Cynthia Nixon) walking through New York and a recap of what happened in the TV series as well as what happened between the season six finale and the film. It then jumps to Carrie and Big (Chris Noth) viewing apartments with the intention of moving in together. Carrie falls in love with a penthouse suite far from their price range, which Big immediately agrees to pay for. However, Carrie experiences doubts over the wisdom of this arrangement, explaining that they are not married, and as such she would have no legal rights to their home in the event of a separation. She offers to sell her own apartment, and quelling her fears, Big suggests that they get married.
Miranda (Cynthia Nixon) is finding balancing her home, work, and social life ever more difficult, and confesses to the girls that she hasn’t had sex with Steve (David Eigenberg) in six months. She is devastated when Steve reveals he has slept with another woman, and immediately separates from him.
After an argument with Steve at the rehearsal dinner, Miranda, still upset about Steve's indiscretion, tells Big bluntly that he and Carrie are crazy to be getting married, as marriage ruins everything. On the day of the ceremony, Big cannot go through with it, but repeated attempts to telephone Carrie fail. A devastated Carrie flees the wedding. Big changes his mind and intercepts Carrie as he sees her limousine drive away. Carrie, humiliated and betrayed, furiously attacks Big with her bouquet while he earns scathing looks from Miranda and Charlotte. The four women subsequently take the honeymoon that Carrie had booked to Mexico, where they de-stress and collect themselves.
Upon her return to New York, Carrie hires an assistant, Louise (Jennifer Hudson), to help her move back into her old apartment and manage her administration. Charlotte learns she is pregnant after a visit to her doctor. Miranda eventually confesses to Carrie about what happened during the night of the rehearsal dinner, and the two have a brief falling out. After reflecting on the argument she had with Carrie, Miranda agrees to attend couples counseling with Steve, and they are eventually able to reconcile. Samantha begins over-eating to keep from cheating on Smith with Dante, but eventually realizes that their relationship is simply not working, and that she needs to put herself first. The two break up, and she moves back to New York. Charlotte for several months is concerned that something might happen to the baby, because she feels her life seems to be too perfect.
A surprise encounter with Big at a restaurant leaves Charlotte so outraged that she goes into labor. Big drives her to the hospital, and waits until baby Rose is born, hoping to see Carrie. Harry passes on the message that Big would like her to call him, and that he has written to her frequently, but never received a reply. Carrie searches her correspondence, before realizing that Louise has kept his e-mails password-protected from her, after Carrie earlier announced she wished to sever all communication with him. She finds that he has sent her dozens of letters copied from the book she showed him in the weeks before their wedding, Love Letters of Great Men, Vol. 1, culminating with one of his own where he apologizes for screwing it up and promises to love her forever.
One hour before the locks are due to be changed on their shared penthouse apartment, Carrie travels to the home Big had bought for them to collect a pair of blue Manolo Blahnik shoes she had left there. She finds Big in the walk-in closet he had built for her, and the moment she sees him, her anger at his betrayal dissipates. She runs into his arms and they share a passionate kiss. After they have spent the final hour in their apartment together making up, talking and apologizing to one another, Big proposes to Carrie properly, using one of her diamond-encrusted shoes in place of a ring. They later marry alone, in a simple wedding in New York City Hall, with Carrie dressed in the original dress she had bought in a vintage shop and the blue Manolos. After Big kisses the bride, he whispers into her ear "Ever thine. Ever mine. Ever ours," a line by Ludwig van Beethoven Carrie read to him from Love Letters of Great Men, Vol. 1 earlier in the film. They hold a get-together at a local diner with their friends. The film ends with the four women around a table in a restaurant, sipping cosmopolitans, and celebrating Samantha's fiftieth birthday, with Carrie making a toast to the next fifty.
