It’s been a busy summer. Francesca is working in New Zealand, Roxy’s Sasha is at Princeton in a program for gifted children, Stella is still struggling with her acting career and Gigi and Payne are moving in together! While at a preview of a charity auction of Liz Taylor’s memorabilia, Gigi and Payne are so aroused by their surroundings that they have sex in the pretty pink recreation of Taylor’s bedroom. Happy just to be with Payne, Gigi’s thrilled when he presents her with a ring. Her joy is killed when she later learns that the faux bedroom was rigged with surveillance cameras.

Celebrating Gigi’s new singledom, Roxy and Stella drag her to the legendary Hustler store for new sex toys. Roxy and Stella, on the way to pick up Sasha at Princeton, take their purchases to try out en route. While her friends are away, Gigi finds she’s been replaced as Rick’s beard but things aren’t too bad since she’s landed a gig on a sitcom. Peter, the blind head-writer, a fan of Gigi’s work for years, wants to write her into the show as a regular and pitches her ideas as Gigi changes in front of him—he can't see anyway, right? Visiting her estranged husband, Paul, in the hospital where he’s preparing for transgender surgery, Roxy learns he’s having second thoughts—and that they're still in love.

Rick accidentally saves the life of his stunt double in a car explosion that Rick actually caused. With headlines splashed across the papers, Rick is labelled a hero and is named official spokesperson for the International Paediatric Burn Society and invited to speak at their conference in Paris. When he invites Gigi to accompany him to Paris, Gigi is thrilled even though she’ll have to spend the weekend doing traffic school online because of a recent traffic violation! At the airport, Rick reveals to her that he’s smuggling drugs by hiding them under a bag full of gay sex toys—security never checks! In Paris, while Gigi is at the computer, Rick spends his time in a tanning booth with the guy from the tanning salon. On the day he’s to give his speech, his face breaks out into horrible welts from the tanning solution. At the Paris airport on the way home, Rick’s decoy doesn’t deter the French agents from searching his bag and he’s nailed for drug possession.

With a thunderous rainstorm raging outside, Roxy is happy to have Paul staying with her and Sasha. Unfortunately, that’s no real comfort to Gigi, whose roof is leaking. When Stella calls from the Laundromat to tell her a house collapsed in Laurel Canyon, Gigi heads to a hotel for the night. Sound asleep, she awakes to a ghost who gives her the most amazing orgasm of her life. The following morning, Gigi remains convinced that she had sex with the ghost of the founder of the hotel, but her friends think she's crazy. Rick is recovering from a night of hard partying at his network exec's house and begins to recall a kinky incident that occurred. It makes Rick realize he needs to sober up. He arrives at Gigi’s that night and gives away his plentiful stash of drugs. The girls try to support him in his sobriety, but it makes for a pretty boring evening. Stella, meanwhile, has been spending time with JC at the Laundromat and finally brings Gigi to meet him. The girls are both a little surprised when JC announces he’s Jesus Christ. Roxy is in her own world of confusion when she arrives home one day to find Paul in drag.

The beautiful and successful Livia, Gigi's friend and neighbour, is back in town! She’s been away for 18 months on a documentary shoot in Papua, New Guinea and the girls celebrate her return with a dinner. They are enthralled by Livia’s stories and in awe of her life as a lesbian who garners a lot of attention from men. The following day Livia introduces Gigi to Jackson, a handsome and fabulously wealthy documentary filmmaker. She is instantly smitten. However, she soon discovers his fatal flaw when after a wonderful session in bed, she finds him sleeping in a bathtub filled with water— a trick he learned in Tanzania to alleviate his back problems. Meanwhile, Stella has decided to see a plastic surgeon about her laugh lines. She’ll undergo peniscryn—the injection of cells from a baby's foreskin into her face—a procedure touted as “better than botox.” Roxy’s world is shaken after a blowout with Paul and she seeks Livia’s advice.

Despite Jackson’s strange sleeping habits, Gigi is making it work. She’s also landed the lead in a comedy film. With the new movie and a rich boyfriend, she’s decided to wear only designer labels from now on and donates bags of clothes to a local thrift shop. Shortly thereafter, Jackson tells her his new documentary has been green lit, and he’ll be going to Tanzania for three months. They decide to continue their relationship long-distance but Gigi is crushed. Meanwhile, Roxy and Paul decide to reunite and seek therapy and Stella gets busted acting as her agent in a local restaurant. On the set of her film, Gigi immediately notices Duff, a gorgeous props guy from Canada. With his stay extended to 18 months, Jackson breaks up with Gigi. Duff, who’s been hovering nearby, "consoles" her in her trailer moments later. Having grown accustomed to the idea of dating someone rich, Gigi can’t possibly wrap her head around the idea of dating Duff—plus he’s Canadian. But when Gigi is fired from the film and she and Rick can’t convince the thrift store to return her clothes, Duff arrives at her doorstep with her wardrobe from the movie, and Gigi wonders if maybe there is a future?

When Duff takes Gigi on a picnic to celebrate her best actress nomination for "Deep Snake,” Gigi discovers he's great with kids, which makes her even more attracted to him, but she would still rather date someone with money. Far from maternal, Gigi is inclined to offer to look after Sasha while Roxy and Paul go on couples retreat. The weekend with Sasha is a disaster until Gigi confronts Sasha about her attitude, and Sasha breaks down about her home life. They bond over a breakfast of pizza and the movie "Jackass," which Duff dropped off on his way out of town. Roxy is thrilled to see that her friend and daughter have connected when she and Paul return from the retreat.

At Livia’s encouragement, Gigi has decided to take advantage of all the "Deep Snake" publicity and throw a big Hollywood party. She’s desperately trying to pull the party together with only a few days notice when her sister and brother-in-law, swingers from Edmonton (the wife-swapping capitol of Canada) drop in for an unannounced visit. Gigi's less than thrilled about having her star-crazed sister Gwen at her swanky soiree. What starts out as a fun idea quickly turns into a nightmare—no celebrities show up, the caterer serves veal to vegans, Stella's boyfriend goes into anaphylactic shock from the peanut oil in Stella's edible underwear, Paul chooses to attend dressed as a woman and Rick gets him so high he ends up making out with Livia's girlfriend Diana, who bears an uncanny resemblance to Roxy, right in front of Livia and Roxy. To top it off, Gigi finds Gwen and Brian in bed with Rick. Duff arrives and Gigi realizes how much she loves him. She asks him to take her up to the lake he loves so much and they flee the party – and maybe Hollywood – for good.
