Frustrated with being single and only being hit on by talking sandwiches, Miranda tries out multi-dating where she learns being a corporate lawyer isn't doing any favors for her sex appeal. When she pretends to be an airline stewardess though, she catches a date with Harris, an emergency room doctor. The morning after one of her spark-filled nights with Harris, Miranda cuts her finger, only to learn that Harris isn't a doctor after all. Instead of fessing up to her own impersonations, Miranda acts disgusted and tells Harris to leave. Meanwhile, the girls go out on the eve of the Charlotte's wedding, for her last night as a single woman. Everyone is totally stunned by Charlotte's admission that she and Trey haven't had sex yet. But after more drinks than she can handle, Charlotte shows up at Trey's place ready to get busy. Unfortunately though, things don't work out in bed for Trey, and Charlotte gets a little nervous. Carrie's nerves are also getting the best of her as she considers whether to tell Aidan about her affair with Big. Just minutes before Charlotte's wedding, Carrie drops the bomb. Aidan is devastated and walks off. At the wedding, Charlotte gets last minute jitters about Trey's sexual under-performance, but Carrie calms her down with a white lie, and Charlotte walks down the aisle. Aidan shows up after the wedding and says he loves Carrie, but knows he will never be able to let go of the fact that Carrie cheated. Carrie breaks down crying, but takes some comfort in knowing that at least she has three friends who love her no matter what she does.

Still away from New York, the girls embark on week two of their Los Angeles adventure. Hoping to get away from the happy superficiality of LA and reconnect with her neurotic roots, Miranda gets together with Lou, an old New York friend. But instead of trashing LA as Miranda hoped, Lou says the city has taught him to let go of his toxic anger. Meanwhile, Carrie and Samantha try to live the quintessential LA. scene by going to a movie screening party - but they're rejected at the door. Luckily, Carrie meets Keith, who gets them into the party. Wowed by Keith's status, Carrie goes on a date with him and ends up in bed at his fabulous home...until Keith's boss comes in the house and lets the cat out of the bag -- Keith isn't a television mogul; he's a personal assistant. Back home, after another failed attempt to have sex with Trey, Charlotte decides she misses her friends and hops on a plane to LA. Over lunch, Charlotte breaks the news that her marriage is fake, and they're not having sex -- the girls are stunned. And in a last ditch effort to be LA women, the girls all head to Hugh Hefner's Playboy mansion for a pool party. Charlotte meets a charming older man, who offers to buy her a boob job, and Samantha gets them all kicked out for accusing one of the bunnies of stealing her fake Fendi bag.
