The O.C., Season 4

In the fourth season of The O.C., high school seems like a distant memory for the young graduates, who have been thrust into adulthood after the death of their beloved friend Marissa. The Cohens struggle to keep Ryan focused on the future, fighting the forces that threaten to pull him back into his old life. Having left Orange County, Summer attends Brown University in Rhode Island, where she has reinvented herself as a left-leaning, tree-hugging activist. And, lonely in Orange County, Seth works at a local comic book store.
