Forced to attend summer school following the police crashing Naomi's after-prom party, Naomi, Silver and Adrianna form a tight bond with one another, while Annie finds herself more isolated from her friends and family as she worries about her hit-and-run. As summer draws to a close, the gang hangs out at the Beverly Hills Beach Club, where Naomi and Silver meet Teddy, the son of a famous movie star. Meanwhile, Dixon and Silver work to save their relationship, but it may be too little too late.

Annie is humiliated that the entire school received her sext message and is on a mission to reveal Naomi as the sender of the revealing photo. Harry and Debbie attempt to discuss Annie's situation but the conversation only causes more tension, leading Harry to open up to Kelly about his family problems. Dixon meets his dream girl, Sasha and sparks immediately begin to fly, though he fails to reveal his true age. Silver continues to get over Dixon while Adrianna and Navid deal with Teddy's presence in their life. Liam, fed up with the lies between Naomi and Annie, retreats to his garage to work on a mysterious project. The gang joins Teddy on his father's yacht for an afternoon of ocean-filled drama.
