Prompted by a disturbing phone call earlier, Kim and Kyle confront Taylor about using alcohol as a crutch. Taylor then turns down a group trip to Paris in order to spend time with her daughter. The rest of the ladies, however, jet off to the City of Lights for fun and fireworks. They're worried, however, when Kim is late then acts increasingly strange, in a way reminiscent of her life before rehab. Lisa and Ken also take a side trip to San Tropez, where they reunite with Ken's grown son and his much-older wife, who was once a friend of Lisa's.

The ladies' trip to Paris wraps up with a boat ride down the Seine River, and an unlikely bond forming between Kim and Brandi. Back in Beverly Hills, Lisa begins planning her housewarming party/vow renewal with flamboyant party planner Kevin Lee, and Kyle scurries to prepare for her boutique opening. In a changing room during the big event, Kyle and Kim discuss Kim's erratic behavior in Paris, and Kyle wonders if she'll ever be able to trust Kim's sobriety.
