In the Season 5 premiere, Sonja kicks things off with a party to mingle with Aviva, Carole and Heather. They all seem to hit it off. . .until Ramona arrives. And as they say, with new friends come new revelations -- in this case, Aviva learns that a couple of her "new" friends have had relations with her ex-husband. Meanwhile, Heather and Carole try to figure out who to trust and not. Picking up right where they left off, LuAnn is still annoyed with Ramona about the disparaging comments she made about LuAnn's parenting (from last season) and tries to discuss it with her at the party, but Ramona has no interest. Things get interesting as Sonja, Ramona, Heather, and Aviva head to the Hamptons for the weekend and once back in the city, LuAnn surprises the new ladies with a shocking story. The three new women agree to never become "mean girls."

To settle their differences, LuAnn and Ramona finally meet up to clear the air. LuAnn wants Ramona to own up to blackmailing her, but Ramona sees it differently and denies any wrong doing. Carole and Aviva head downtown for shopping and chatting while further uptown, Sonja assesses the severe water damage caused by Hurricane Irene to her townhouse. Will flirting with contractors help her? Meanwhile, Ramona gets upset after a lunch with Aviva where she discovers LuAnn's been a little too chatty and when Sonja goes M.I.A. at a GLAAD Awards event, no one is surprised by how she ends the evening.

Uptown ladies Aviva, Heather and Sonja take a trip downtown to Carole's cool neighborhood where she hosts an afternoon of brunch, booze, and bitching that includes New York's most popular ex-husband, Harry, Carole's commitment phobia, and Aviva's fear of just about everything else. With her townhouse falling in on her, and no settlement in sight, Sonja attempts to take charge of her financial future by launching a catering company. Always hard at work, Heather decides to mix business with pleasure and invites SOME of the ladies to join her on her next business trip to London. Things get interesting when the ladies come together to celebrate a jewelry launch and Ramona takes the opportunity to apologize to Heather but gets a cold shoulder from LuAnn, who might not be ready to bury the hatchet.

Ramona invites Aviva, Carole, and Sonja for lunch to discuss her current issues with Heather, however, Sonja chooses to have a secret rendezvous with LuAnn instead. LuAnn voices concern that Ramona has control over Sonja, but Sonja sets the record straight. Always the journalist, Carole and her friend Tripp head downtown to witness the Wall Street protest, where they takes photos, sign petitions, and Carole talks about her time working at ABC News. In order to resolve their issues, Ramona agrees to meet Heather for drinks hoping to get an invite to the London trip but the drinks take a turn for the worse when they actually get talking. Aviva and Heather have a night out where Aviva informs a suspecting Heather that because of her phobias and family, she won't be going on the London trip. Meanwhile, Sonja hosts a party in honor of her new magazine cover and Ramona pressures her for going on the London trip without her. . .leading to the first rift in their friendship and many concerns.

Aviva and Heather meet up to discuss the London trip, to which Aviva expresses concern over the exclusion of Ramona -- but Heather is not fazed in the least. LuAnn heads to an acupuncturist to see what she can do about having a baby. Meanwhile, Aviva asks Sonja to throw a fifth anniversary party for her and her husband. Sonja is ecstatic that it will be Sonja in the City's first event, although she's concerned that most of the planning will take place while she is in London. Carole decides to go on a date with a guy she met through Sonja and things seem to be going well. . .until she finds out his age. Later, Carole and Ramona meet for tea to talk about Ramona's issues with Heather and as she gets worked up thinking about the situation, Carole tries to distract her by telling Ramona that she is a princess. Ramona is over the moon knowing that Carole has one up on LuAnn. In an attempt to smooth things over, Heather invites Ramona shopping along with Aviva and Carole. When Ramona and Hea

Carole, Sonja, and LuAnn arrive in London and live it up in a gorgeous penthouse Heather arranged for everyone. As Heather is busy working, the women shop in Notting Hill, and Carole lets the ladies in on her life in London after her husband died. Later on the ladies experience how Heather's Yummie Tummie business is run and get a few surprises when they join a work dinner. Back in the Big Apple, Ramona and Aviva also go shopping -- but this shoe shopping experience has Ramona shocked and amazed with Aviva's prosthetic leg. And Ramona lets New Yorkers know how you can have it all when she gives a speech at The Learning Annex. The London ladies stay in for a night and have a slumber party. They laugh, play games, and bond over dinner in the suite, while gossiping about Ramona. At the same time, Ramona and Aviva double date with their husbands back in NYC. Ramona comments that they are having a much better time than the London crew because there's probably no way anyone can get a word

Sonja, Heather, LuAnn and Carole play croquet; Aviva is concerned by Sonja's lack of party planning; Aviva falls down the stairs at the party.

Ramona, Sonja, Carole, and Aviva meet for lunch to discuss London and the Anniversary Party. Aviva mentions going to Miami with Ramona and extends an invitation to Sonja to be set up with her sex-crazed father. Carole, coincidentally, will be in Miami at the same time. Heather brings Sonja to her office to meet with James Bernard, a logo expert, to help Sonja with her brand, but things go south quickly. Later that night, LuAnn and Jacques host a wine event and invite all the ladies. They have Ramona sit down with the Master of Wines to do a blind tasting, but when she's in the hot seat, they fail to mention it's actually her wine they're showcasing. Sneaky or all in fun? Down in Miami, Aviva and Reid get ready for Ramona and Mario's arrival and when Carole meets up with her good friend Ranjana, she learns some disturbing news about LuAnn.

Carole and Sonja head to sunny Miami to meet up with Aviva and Ramona. Aviva hosts a dinner for all the ladies, their husbands and her sex-addict dad, George. George immediately has eyes for all the ladies, including his "date," Sonja, and even tells Carole that he can do inappropriate things to her. Back in New York, Carole and LuAnn go shopping to look at some jewelry. Carole calls LuAnn out for asking her friend to loan her dresses. On the last night in Miami, the ladies, their men and George head over to the Art Basel festival. Even though Sonja seems to have made it clear that she’s not interested, George is still trying. As the entertainment begins, Aviva pulls Sonja aside to ask how she deals with Ramona. The ladies return to the rest of the group and toast to a great Miami vacation.

Heather and her branding team of experts head to Sonja's house for their second meeting and much to their surprise, Sonja has invited Ramona over as someone in her court to chat business and ideas. Later that night, Ramona invites all of the ladies and their significant others out to dinner -- except for Heather. But things go awry quickly as LuAnn offends Carole and Mario takes issue with Jacques. Over lunch, LuAnn confides in Sonja that she's trying to have a baby with Jacques. Sonja worries that LuAnn is doing it for the right reasons. Finally, LuAnn hosts a holiday party that all of the girls attend, and a very drunk Sonja confronts Jacques (and LuAnn) about some very personal issues. And to top off the night, the ladies get up on stage to sing, accompanied by the punk band that LuAnn hired, but the band finishes up the night with a surprise (and inappropriate) song of their own!

To celebrate the holidays, Carole hosts a "White Elephant" party for the ladies and their husbands. Aviva brings her father George, who happens to be in town and LuAnn and Heather get their first dose of the sex-crazed patriarch. Sonja arrives to her toaster oven photo shoot over an hour late -- which immediately ticks off Heather, who has organized the entire thing. When they finally begin shooting both campaigns, Heather and her team know their campaign is better, but will Sonja? Carole has all the ladies over to her apartment to tell them some big news. She finally finished her book and wants to celebrate -- by inviting all the ladies to come with her to St. Barth's for a vacation. The women can't wait to go, minus Aviva who also has a phobia of flying. Sonja invites all the women to a friend's party and Aviva finds this a perfect time to ask LuAnn about the wine incident with Ramona, which confuses LuAnn as she's already hashed it out with Ramona, and she questions Aviva's in

Aviva hosts a charity event at Soul Cycle to raise money for children who need prosthetics. Ramona and Sonja are no shows, which angers Aviva, who thinks that if booze was served, they would’ve showed up to support her. Aviva and Carole meet at a jewelry store where Aviva tells Carole she's most likely not going to make it to St. Barths because of her fear of flying. After raising money at the Soul Cycle event, Aviva brings Carole and her son, Harrison to "A Step Ahead," where she presents a young boy named Jake with a pair of prosthetic running legs.

The ladies arrive in St. Barths, without Aviva who stayed back due to her phobias, and head straight for their beautiful villa and realize it's first class all the way around. On their first evening Russ, Carole's boyfriend who is on the island for a blues festival, shows up just in time to meet the women and save the conversation and the rest of the evening. A night out at Le Ti has the ladies enjoying tequila shots and a pirate-themed performance, led by the ladies' liaison, Tomas, a hot Johnny Depp look-alike. The next morning, rumor has it LuAnn kept the party going much later than anyone else.

The ladies have invited friends over to the villa for a party, but only two people show up -- Cat, LuAnn's old friend, and Tomas, the "Johnny Deep look-alike" from the night before. The ladies think it was Tomas that LuAnn brought back to the villa the previous night and Ramona takes the opportunity to get to the bottom of it. The next day the ladies head out for a calming and fun day on a yacht. Meanwhile Aviva and Reid are en route to St. Barths, despite Aviva's fear of flying in small planes, but when they arrive, Aviva doesn't receive the warm welcome from them that she was anticipating.

While Aviva, Reid, Carole, and Russ are busy setting up a double date, Ramona realizes that the girls trip she thought they were on has definitely turned into a couples retreat. As Carole tries to explain to Ramona that it will be a quick dinner, the discussion quickly escalates and takes a turn for the worst when Aviva walks in. On the final night, the women go out for an early drink before taking off to see Russ perform, but Sonja and Ramona add fuel to the fire when they opt to return to the villa instead of going to the concert.

The wives return from their vacation, but fallout from the trip creates dramas. Elsewhere, a surprise awaits Carole when she crosses paths with a former suitor.

Aviva's father returns and visits a health-food store with his daughter; Sonja negotiates a settlement with her former husband; and Heather preps for her fashion show and has a surprise request for Aviva.

Social events spin out of control in the Season 5 finale. Here, Ramona is seemingly at the center of showdowns, including Heather's fund-raiser (Ramona vs. Sonja) and Carole's book party (Ramona vs. Heather, plus Ramona vs. Aviva).
