The beautiful, wealthy ladies of Beverly Hills and the sexy, dramatic servers of SUR are back for a special two hour crossover event. To celebrate the centennial of Beverly Hills and meet other local business owners, Kyle throws a cocktail party at her home for the city's Chamber of Commerce. She hires Lisa's posh restaurant, SUR, to cater the event but in typical fashion, one of her servers begins talking back and Lisa has to send her home before the guests begin to arrive. At the party, Kyle tries to put aside her differences with Yolanda after last year's explosive reunion, while Lisa struggles to keep tensions down between Brandi and Scheana. After the party wraps up, SUR staffers Stassi, Jax, Katie, Tom and Scheana head out to meet up with Kristen when serious tensions flare up. In an effort to mend her relationship with the group, Scheana invites everyone to her birthday party, but it doesn't take long for catfights to erupt.

Carlton hosts the ladies for a luncheon in her gorgeous, Gothic mansion, which sports "Victorian balls," a spooky doll collection and black cats. When Lisa shows up to the lunch a little late, teasing from her friends about her suspect faint proves too much for her after recently being eliminated on Dancing with the Stars. Kyle upsets Carlton by asking too many questions about witchcraft, but Kyle finds herself on the defense when Brandi prompts the ladies to talk about the tabloid accusations about Mauricio cheating.
