Welcome to Potomac, where proper etiquette is key, and breaking the rules comes with serious consequences. At a birthday party celebrating Karen Huger, grande dame of Potomac high society, Gizelle Bryant’s lack of manners puts the two divas into a battle for supremacy. And as if that wasn’t enough, Gizelle is under fire from Charrisse Jackson Jordan, for acting not very lady like in her plush home. International model Katie Rost, a divorced socialite with three toddlers, is doing everything in her power to get her boyfriend to put a ring on it. Meanwhile, Robyn Dixon, who lives with her ex-husband, former NBA star Juan Dixon, must decide if she wants to rekindle her relationship with her ex.

Gizelle’s reputation is called into question by Potomac's queen bee, Karen, and its self-appointed social director, Charrisse. Will they be able to play nice, or are these domestic divas going to take off their white gloves and get dirty? Katie has to tap into her Jewish roots to prove herself a true member of the tribe for her twins' naming ceremony. Things get a little dicey when the ladies meet the young, boisterous beauty queen Ashley Darby. Will Ashley be able to break into this coveted circle of sophisticated women?

In Washington, D.C., Katie socializes to attract attention to her family's charitable foundation; Robyn faces a choice that threatens her unconventional relationship with ex-husband Juan; Ashley hosts a whiskey-tasting event in downtown D.C.

Katie renovates the house behind Andrew's back; Charrisse tells her friends the shocking truth about her 18-year marriage; Karen learns how to fly a plane; Ashley gossips online, incurring the wrath of her close-knit community.

Karen organizes a couples' getaway on a yacht, and Gizelle's new suitor scores an invite to the cruise. Also, Katie makes waves by showing too much public display of affection at Ashley's birthday bash, and news about Charrisse's marriage shocks Robyn.

Ashley tries to wow her new friends with a getaway to her Delaware beach house, yet the accommodations fail to impress. Elsewhere, Katie struggles to gain support, and Charrisse convinces the ladies to reveal their darkest secrets.

An evening of bonding takes a tense turn when Gizelle confronts Katie, prompting the others to encourage Katie to put Gizelle in her place. Elsewhere, Ashley's newfound friendships come into question courtesy of a surprise from her husband.

Gizelle's inner entrepreneur takes center stage, but the shade is real when Katie blows off a focus group for her budding makeup line. Juan and Robyn take a romantic trip down memory lane, making her more confused than ever about the state of their relationship. Karen launches a charity event close to her heart, but Ashley and Michael must get "on par" before they are welcome in her home. And will Karen push Ashley one-step too far?

Whether or not her husband, Eddie, shows up for the big party, Charrisse is determined to celebrate her 50th birthday to the tune of $80,000 of his money. The future of Robyn and Juan's relationship hangs in the balance as they finally get the news about a possible job out of state. Ashley and Karen's friendship may have reached the point of no return.

Katie and Andrew's relationship takes a turn when he surprises her with a weeklong trip to Scotland . . . that he's taking without her. Hearing her biological clock ticking at the ripe old age of 27, Ashley puts pressure on a reluctant Michael to start having kids. Gizelle hosts a "come to Jesus" lunch to try to get friendships amongst the ladies back on track. Karen takes off the white gloves and reads Ashley for filth, while an uproar ensues between Katie, Robyn, and Gizelle over butt grabs and biracial labels.

Fevers spike as Gizelle, Katie, Ashley, and Robyn try to pull Karen off her podium as the Grande Dame of Potomac. Ashley defends her hostessing, her husband and her humping despite the slings and arrows of shade-rageousness. Robyn makes a surprising admission about her feelings for her ex-husband. And questions about the sensitive topic of race spark a high-octane feud.

Katie's revelation about her relationship with Andrew leaves everyone wondering if she's headed down the aisle or out the door. Karen's husband, Ray (the "Black Bill Gates"), and Ashley's husband, Michael, join the ladies to weigh in on Michael's surprise visit to the girls' beach trip and his dance-floor butt grab that sent shockwaves through Potomac. Charrisse reveals just how close her marriage is to destruction. And Gizelle and Katie battle over shocking allegations, leaving all the women to wonder who's right and who's wrong.
