After spending several days in the hospital recovering from a near-fatal drug overdose, Adrianna tries to make amends with Naomi. But Naomi refuses to forgive Adrianna for her betrayal. While serving her detention, Naomi meets a trouble-making punk, named Ozzie, who could spell trouble for her. Later, Adrianna makes a connection with Navid, who helps her through her situation as she's accepted into a rehab clinic. Meanwhile, Annie and Ethan finally take their rapidly growing romance to a new level during the school's annual homecoming dance, causing Naomi to feel jealous. Dixon asks Silver to the dance, but she turns him down for she feels, in her liberal and radical mind, that Homcomming is the scene of the morally corrupt. Ryan believes that the new student, Kimberly, is a narc after he sees her purchasing drugs. Also, Debbie confronts Tracy about the time Tracy kissed Harry.

Silver invites a few of her female friends over at her house for a girls' night, but the event quickly turns into a house party which causes massive damage to hers and Kelly's house. Meanwhile, Debbie and Harry finally reveal to Dixon and Annie that they have a long-lost, out-of-wedlock brother who was given up for adoption by Tracy Clark over 20 years ago. Dixon, who does not appear upset by the news, deals with the situation by talking to Silver about it. However, the news bothers Annie and she takes out her anger and frustration at Silver's party by getting drunk and being insulting to everyone. Annie and Ethan decide to keep their relationship a secret, while Naomi continues to hang out with the trouble-making Ozzie. Elsewhere, Adrianna and Navid continue to grow close until they have a misunderstanding. Also, a student sees Ryan and Kimberly kissing and begins to make demands to Ryan, while Kimberly is just determined to keep her secret identity under wraps at any cost and informs Harry about what's transpired between them.

Harry and Debbie welcome Sean into their home, while Dixon, Annie, and Tabatha welcome him awkwardly despite the fact that they don't know much about him, while Naomi and her mother, Tracy, welcome him to their home as well. Meanwhile, Kelly and Brenda's friendship is slowly fading away and gets wider after Brenda is hospitalized from an accident and confides in Kelly that she seduced Ryan weeks earlier. Naomi decides to hang out with a new group of girls at school despite Ozzie's advice that they want nothing to do with her. Also, Silver feels threatened when a cheerleader, named Christina, shows too much interest in Dixon who shares the same interests he does.
