When the rest of the gang takes off on a ski weekend, Brenda stays behind and discovers an old diary that belonged to a young woman who once lived in the Walsh house with her parents and brother in the late 1960s, in which Brenda imagines herself and the gang as the girl Wendy and the gang as her hippie friends.

Emily flies back from Paris to attend a seminar at La Jolla. She asks Brandon to meet her at the airport, claiming to have just a four-hour layover. She actually has a week until the beginning of her seminar, but Brandon breaks her heart by revealing that he is dating Kelly. When he sees her back to her hotel room, they share a passionate kiss. Steve and Griffin organize a holiday rave at an abandoned house. Valerie helps them out in the hopes of getting back in Steve's good graces. David and Clare accidentally post the notice about the event on a computer bulletin board for lesbians, who constitute most of the guests. The house has very poor wiring and continually blows fuses. Griffin uses too much electricity, and the house catches on fire. Ray rescues Steve and Valerie, who were fooling around in one of the bedrooms. Kelly and a girl named Allison are trapped in a downstairs bathroom with no means of escape. The firefighters try to reach them as they are engulfed by flames.

In the aftermath of the house fire, Kelly suffers second and third degree burns on right wrist, ear, and the whole right side of her neck. Allison's injuries are much more severe, but she maintains a positive attitude. Brandon is racked with guilt because of his feelings for Emily. Kelly does not react well when she learns that Emily is still in town. She calls Dylan to discuss her insecurities and Brandon visits him in search of advice. Kelly believes that Brandon is only staying with her out of guilt, but Emily eases her mind when she reveals that he expressed his love for Kelly before the fire. Meanwhile, Steve feels guilty for the house fire and calls upon his father, Rush, to help out. Griffin's father hires an accomplished attorney for Steve and Griffin where Rush advices both to plead guilty to criminal trespassing in order to avoid jail time. Steve and Griffin receive two years of probation and community service... and are forbidden from operating dance clubs or parties for two years. Steve is furious to learn of this provision, especially after he discovers that Griffin in fact stole the keys from his father's real estate office to the house, rather than obtaining permission to use it for the rave. Steve tells his father that he didn't know about what Griffin did, but Rush (being more arrogant and narrow-minded) refuses to believe Steve and tells him not to ever call on him again for help. Afterwards, Steve physically attacks Griffin and orders him to leave the fraternity. Elsewhere, Ray's perpetual bad mood confuses Donna. He explains that his mother always begins drinking around the holidays, as his drunkard father left her on Christmas... after pushing her down the stairs and causing her to have a miscarriage. Andrea and Jesse throw a party for Hannah's first Hanukkah. Jesse obtains work as an attorney for those who cannot afford representation. He is frustrated by the court treatment of a single Mexican immigrant father, whose kids are taken away when a babysitter neglects them. At the end, Dylan comes home from rehab and is greeted by a letter from a stranger who found Erica's bathroom note pleading for his help.

Kelly finally becomes a cover girl on Seventeen magazine, but hesitates to continue modeling due to her fire burn scars. While coping with her newfound stardom, Kelly learns that she has a new admirer: the horribly scared Alison from the fire that night. Ray returns to Beverly Hills and to a bravo return appearance at the After Dark. But Ray's mother LuAnn, in an intoxicated state, ends up tipping off David and Clare about his unfaithfulness to Donna with Valerie. After David and Clare confront Ray, and then Valerie, they decide not to tell Donna to avoid hurting her feelings. Meanwhile, Andrea thinks about her future after Jesse is offered a law position in Idaho. Also, Dylan continues talking with Charlie about the correct script for themselves.
