Brandon meets and befriends surfer Dylan McKay, a mysterious loner who lives in a fancy hotel suite and hangs out at the beach with his surfer friends that include teenage alcoholic Betty. Meanwhile, Brenda feels she's living in poverty when she gets to know Kelly, and her insecure friend Donna.
Brandon meets Dylan McKay, a mysterious loner who stops some jocks from harassing Scott in tech class. Dylan takes Brandon surfing and introduces him to his friends, including a troubled young woman named Sarah. Brandon becomes disturbed by the behavior of Dylan's friends, who treat Sarah like a possession.
Brandon grows tired of Dylan's bad boy act after he raids a hotel room. Dylan reveals that he lives in the hotel, and only pretended to break in to preserve his reputation. Sarah nearly drowns while surfing drunk, but Brandon and Brenda save her life. Sarah seeks help for her drinking problem, and thanks Brandon for convincing her to believe in herself. Brenda is miffed at Kelly after she leaves her stranded at the beach. Steve's mother, an aging has-been actress, encourages him to be nice to David because she mistakenly believes that David's father is a producer.
