High school seems like a distant memory to the young graduates of Harbor School in Newport Beach, particularly because they have been thrust into adulthood after the death of their beloved friend Marissa Cooper.

After Ryan and Taylor have an accident while hanging holiday lights, they realise that everything is not as it seems, and they must do whatever it takes to make things right again.

Ryan travels to Mexico, with a stubborn Seth in tow, to put an end to his turmoil in the only way he knows how, but he comes up empty in his quest for revenge. Meanwhile, Seth meets some new friends in Mexico, including a Marine who help him find what he is looking for, and Harbor School's new female dean of discipline, Dean Torres forces Kaitlin and Julie to work together on Harbor's clothing drive.

When Summer tries to become the gossip-loving girl she once was, she realises that Brown may have changed her forever. Fortunately, Seth continues to be supportive of the new Summer through all of her endeavours. Similarly, Ryan empathises with Taylor and surprisingly helps her out of a bind. Meanwhile, Julie and Kaitlin attempt to stay out of trouble, but neither can resist temptation.

When Seth visits Summer at Brown, he finds an empty dorm room. Meanwhile, Sandy and Kirsten take advantage of an opportunity to bond with Ryan, who is in a Taylor-induced haze, Kaitlin meets the mean girl of Harbor School and tries to best her by throwing a huge party at the Roberts house, and Julie learns that Newmatch is more than just a dating service. Elsewhere, the truth about Che comes out.
