A troubled youth becomes embroiled in the lives of a close-knit group of people in the wealthy, upper-class neighborhood of Newport Beach, Orange County, California.
       Enemble drama revolving around the young adult community of the Orange County, California, area. A street-smart teen winds up in the midst of the high-class society of Newport Beach, sparking something of an "edgier" take on the "Melrose Place" style premise.

It's been three months since Ryan left to live with the pregnant Theresa in Chino, and Seth subsequently sailed off to Portland to live with Luke and his divorced, gay father. With a week before school will start, Kirsten is furious that Sandy has yet to bring Seth back to Newport. Sandy says that they can't bring him back kicking and screaming, because that will only make him want to run away again. Also in the Cohen household, there's a group of re-modelers led by macho man Archie, creating a new family room and re-designed kitchen, a project that apparently was used to distract Kirsten from going from having two sons in the house to none. Meanwhile, Summer tells Marissa that she's been hanging out with a new kid, but refuses to get close to him, saying she'll never get close to a boy again. Marissa knows just how she feels. She misses Ryan but just can't bring herself to call him to see how he's doing. Caleb's paranoia about being indicted is growing all summer long. Back at the Cohen household, Kirsten calls Seth in Portland and begs him to come home. Seth refuses, saying Newport is an awful place. Sandy decides to fly to Portland to possibly use reverse psychology to convince Seth to come back. He also visits Ryan in Chino to deliver him a plane ticket to Portland, thinking maybe the two could deliver an unbeatable one-two punch combination. It's apparent to everyone in Chino, including Theresa, that Ryan is miserable, and doesn't consider it to be his home anymore. Before heading up to Portland, Sandy speaks with Caleb in a parking garage, as Cal is paranoid his home, the office, and other places might be bugged and the phone lines tapped. Once in Portland, Sandy is shocked to see the level of hostility Seth shows his father. Seth seems content to stay in Portland, and continuing to resent his parents for letting Ryan go, and Ryan for leaving. Back in Newport, Jimmy and Marissa join Kirsten for dinner to keep her company, and Marissa goes into the pool house further fueling her missing Ryan. Sitting on the beach that night, she calls Ryan in Chino, but can't bring herself to say anything, so he lays there listening to her breathe, knowing it's her. Julie tells Marissa she's grounded because she's sick of being ignored. Marissa has a meltdown screaming, crying, and throwing lawn furniture into the pool unable to stand anymore of her evil mother or her evil stepfather. Summer visits the Cohen household with a box of Seth's stuff, telling Kirsten she's there she get rid of anything that ever reminded her of Seth. She dumps the box on the bed, and leaves. Later, just before Sandy leaves Portland he tells Seth that he's fine with him staying in Newport, as long as he knows he's safe and happy. And as Sandy is leaving, Ryan is showing up, making his best attempt to convince Seth to go back. It doesn't seem to work until Theresa calls Ryan at Luke's house, and tells him she's lost the baby, saying the doctor couldn't find a heartbeat. Theresa's mother later reveals that Theresa was lying, and she never lost the baby. It's the next morning as Ryan is to leave that the two, Seth and Ryan, decide maybe going back to Newport would be the best thing for the both of them-and the two return to the Cohen household.

Ryan and Marissa deal with the aftermath of Trey's shooting when Julie maliciously goes to great efforts to protect her daughter by influencing Trey to charge Ryan for the shooting. Meanwhile, Kirsten meets a shady young woman, named Charlotte, at rehab who inspires her to move on with her life. Sandy also takes over running the Newport Group while Julie and Jimmy wait for news about the late Caleb's accountants.

During the last days of summer before college, Seth is working at a comic book store in Newport. Ryan has problems dealing with the issues of the past and pushes himself with his new job. Kirsten is preparing Ryan a "care package" but neither she nor Seth can persuade Ryan to come home since he moved out after Marissa's sudden death. At Brown University, Summer settles into her new dorm room with new friend and roommate Che,who's an activist who wants to rally the students for a protest. Taylor phones Summer from the Sorbonne in Paris to ask about her current living status.
