Welcome to "The O.C.," where the lives of a group of friends and families have forever been changed by the arrival of an outsider to their affluent oceanside community of Newport Beach in Orange County, California. When Ryan Atwood was taken in from the streets of Chino by then public defender Sandy Cohen and his wife, Kirsten, the Cohens had no idea how Ryan's arrival would change their lives and the lives of those around them. Their "adorkable" son, Seth, found a friend and brother in Ryan to share his quirky way of looking at the world--and the trials and tribulations of winning the heart of Summer Roberts, his lifelong crush. Ryan has fallen in love with the beautiful girl next door, Marissa Cooper. But their romance is ill-fated, constantly tested by the young lovers' inability to escape from their pasts.
