In the seventh season premiere of The Real Housewives of Orange County, the women all find themselves dealing with lingering drama from last year. As Vicki finalizes her divorce, she's focused on finding happiness, starting with putting the house up for sale and spending time with her new man, Brooks. Busy mom Alexis has a new job as a morning news show correspondent, and after a three-year feud, Tamra and Gretchen meet to bury the hatchet once and for all. Tamra continues to sell real estate to make ends meet, and shows a very expensive property to filthy rich Heather Dubrow -- a former actress, now mother of four -- whom she later invites to a dinner party at Vicki's house. With tensions high and patience low, Peggy and Alexis come face to face for the first time since last year’s bombshell revelation that Peggy dated Alexis' husband. Will the dinner party be a recipe for disaster?

At Vicki's tension-filled dinner party, Peggy and Alexis reach a boiling point, and Peggy decides to close the chapter on her friendship with Alexis and the other women. Gretchen poses for a nude photo shoot for a charitable cause, while OC's newest housewife, Heather, has it all and isn't afraid to let everyone know it. Meanwhile, Vicki and Tamra go on an overnight trip to Catalina with their boyfriends that nearly ends before it begins when Tamra overreacts and puts Brooks in an embarrassing situation.

Tamra's budding friendship with Gretchen affects Vicki; Alexis and Heather try to make amends over lunch; Vicki and her daughter have a deep conversation about Vicki's new boyfriend; and Slade tries to launch a new career as a comic.

Tamra tries to convince Vicki that her friendship with Gretchen won't overshadow their bond, while on the other side of town, Alexis and Heather meet for a doomed lunch to try and work out their differences. Vicki and her daughter Briana have a heart-to-heart about Vicki's new boyfriend, and Briana informs her mother of an upcoming surgery she must undergo. Meanwhile, Slade is trying out a new career -- comedy -- and against Gretchen's wishes, his routine at the Improv is laden with Housewife-insulting jokes. How will Gretchen react when Slade ridicules her friends in public?

Heather tells Tamra that she and Vicki were the butt of Slade's jokes in his insulting comedy routine, and Tamra doesn't think it's funny at all. When Tamra tells Vicki about Slade's comedy routine, she feels insulted, but is distracted by her daughter Briana's upcoming thyroid surgery, which could reveal if she has cancer. Alexis works herself into a frenzy over her upcoming nose surgery because she's convinced that her doctor must remove her nose entirely from her face to take off the bump. At Tamra's '80s-themed Bunco Party, a friend brings up Slade's jokes and a simmering controversy explodes into full-on conflict. While Gretchen jumps to Slade's defense, Tamra tries to diffuse the situation by revealing a surprise -- much to Vicki's horror.

The Bunco Party takes an uncomfortable turn when Slade and some of the O.C. men, invited by Tamra, join the party. Confronted immediately about the insulting things he said about Vicki in his comedy routine, Slade aggressively defends himself. And though Vicki tries to make a graceful exit, she soon finds herself drawn back inside to have the last word. Jumping to Slade's defense, Gretchen and Vicki get into a vicious screaming match, where Gretchen accuses Vicki of being a hypocrite. And just when everyone thinks the drama is over, Alexis gets defensive when Tamra and Heather call her out on her upcoming nose job. Later, once the party drama has passed, Alexis goes in for her surgery, and Vicki's daughter Briana heads to the hospital to have her thyroid removed, fearing the worst -- cancer.

A nervous Alexis undergoes sinus surgery, where her plastic surgeon additionally removes a bump from her nose. Meanwhile, Vicki is distraught as Briana's thyroid surgery went worse than expected. Tamra visits her doctor and decides to have her breast implants removed. Then, Heather plans a glamorous trip to L.A. to get some advice on opening a restaurant, but who needs freeways when you can take a helicopter? Gretchen watches a rehearsal of the Pussycat Dolls in preparation for her Las Vegas debut, but will she realize that she's in over her head?
