Wanting to keep the secret of her hit-and-run accident hidden at any cost, Annie has spent the summer avoiding everybody, including her parents after they move into a new house. Meanwhile, all the other students (Naomi, Silver, Dixon, etc.) were being made attend summer school after she phoned the police about the after-prom party at Naomi's house, which makes them (especially Naomi) dislike Annie even further. Dixon and Annie's relationship suffers more when Dixon believes Naomi's claim that she thinks Annie slept with Liam. Annie goes into a further decline when she finds out the person she ran into died. Naomi, Silver, and Adrianna have formed a bond and spend their last few days of the summer at the Beverly Hills Beach Club. There, Adrianna runs into Teddy Montgomery, her ex-boyfriend and a tennis pro who is a new student at West Beverly. Also, Dixon and Silver decide to get back together, but he finds out that Ethan kissed Silver before he went away when Teddy tells him and he breaks up with Silver for good. Annie gets drunk with senior Mark Driscoll and sleeps with him in Navid's cabana which was supposed to be for him and Adrianna but then Adrianna decides to wait. On the first day of school, Mark shows his friends a naked picture he took of Annie, which Naomi gets her hands on.
