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 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?
