The O.C. Show Summary

The O.C. - also known as Orange County, California - is an idyllic paradise, a wealthy, harbour-front community where everything and everyone appears to be perfect. But beneath the surface is a world of shifting loyalties and identities, of kids living secret lives hidden from their parents, and of parents living secret lives hidden from their children. 'The O.C'. tells the story of the Cohen, Cooper, and Nichol families, and Ryan Atwood, a troubled teen from the wrong side of the tracks, who is thrust into this world, and who will forever change the lives of the residents of The O.C.
