Lisa and Adrienne's tense summit meeting comes to a head, and one party is left unsatisfied when the other refuses to apologize for things she's said in the past. But problems are set aside temporarily when Kim suggests a group trip to Ojai, California, where the women share a five-bedroom mansion on gorgeous grounds. Kim and Brandi start to forge an unlikely bond, but when Brandi is unable to control her potty mouth, things go south with Adrienne.

Though Kyle surprises her daughter with a present every 16-year-old would want, the happy times in Beverly Hills won't last for long. Lisa has a food tasting at one of her restaurants, but Brandi fears she'll run into the waitress who had an affair with her ex-husband. At the tasting, when asked about her issues with Adrienne, Brandi reveals very personal information that Adrienne has always kept private. When Kim tells Adrienne what Brandi revealed, Paul and Adrienne are livid -- and a battle of epic proportions begins.
