 Andrea Zuckerman arrives in town for a visit as the gang prepares to go to their five-year high school reunion at West Beverly High, where she tells Brandon about her troubled life and failed marriage. Meanwhile, Donna becomes jealous about a Rolling Stones magazine article detailing about Noah s single status, which prompts her to sneak away from the dance and to the Peach Pit After Dark to see if Noah will be true to her. Valerie creates a new persona for herself and David in order to fit in at the reunion. Also, Steve lets his macho image he built of himself take over when an old girlfriend drives him away from his date, Janet, and leads him into a prankish web. Also, Kelly also deals with her past over a former boyfriend that is in attendance.
