Welcome to D.C., the most powerful city in America, where it takes more than money to impress people – it's about political power. With the social season in full swing, Michaele's Polo event caters to those who want to be close to it all, with attendees including the Ambassador of India, Michelle Jones and Republican Lobbyist, Edwina Rogers.

And Cat, the brash Brit and new girl in town, gets a crash course in public relations at Stacie's dinner party prepared by a celebrity chef.
Mary quickly realizes that having Lolly, her adult daughter, move back home comes with bigger burdens than she expected. Michaele makes good on her promise to take Cat and Mary horseback riding, but Mary is far from impressed. Stacie’s attempt to show the ladies “where she comes from” takes an unexpected turn when her down-home, soul food dinner is ruined by one of her guests. Lynda is pushed to her limit when a confrontation with Michaele breaks all the D.C. rules.
It’s off to Paris! After a spontaneous decision by Michaele and Tareq to join Stacie and her husband in Europe, the couples start to bond.

Cat raises suspicions that there may be more than meets the eye with Michaele and Tareq.

A peaceful day at the vineyard turns sour for Mary once Michaele and Tareq start to make devastating accusations about her daughter. The ladies are invited to an event hosted by Edwina Rogers, and Cat decides to spice the night up.

Cat loses a dear friend and is devastated by the loss, feeling alone while her husband is out of town. Tareq has family troubles yet again and Michaele realises it's taking a toll on her.
Cat finally puts the finishing touches on her book before sharing some of the juiciest bits with the rest of the housewives, all of which inspires Michaele and her husband to seek a lucrative Book with author Matt Carson who eventually backs away from the deal. During a fun night with the housewives and their families, an argument between Cat and Stacie's friend Erica breaks out and gets heated, bringing one of them to tears.
