When Kathy skips the flight home from Aspen, whispers surface about a meltdown directed at Kyle that took place the night before. Back in Beverly Hills, Erika tells Dorit she's hurt that Garcelle talked behind her back and vows to say it to her face. Sutton and the others don flapper dresses for Crystal's swank Roaring 20s birthday party. However, when Kathy arrives as if nothing is amiss, Lisa heads for the exit, and Erika decides to share what she heard.

Garcelle celebrates her success with a big party and makes an even bigger purchase with some encouragement from Sutton and Crystal. Lisa's refusal to accept Kathy's apology leaves Kyle holding the bag for her sister. As the ladies are draped in diamonds at Kyle's charity gala, stories swirl in the tabloids and Dorit wonders if there is a leak in their circle. Erika and Lisa continue to call out Kathy, leaving Kyle to question if any of her friends can truly be trusted.
