The drama followed the intertwined lives of the Cohen, Cooper, and Nichol families.

Ryan, a teenager who found himself on the wrong side of the tracks, finds himself in well-to-do Newport Beach.

He is taken in by a lawyer and his family and winds up in the middle of wealthy high schoolers and their snarky attitudes and angst.

The OC stared Peter Gallagher as Sandy Cohen, Kelly Rowan as Kristen Cohen, Ben Mackenzie as Ryan Atwood, Mischa Barton as Marissa Cooper, Adam Brody as Seth Cohen, Chris Carmack as Luke Ward, Tate Donavan as Jimmy Cooper, Melinda Clark as Julie Cooper, Rachel Bilson as Summer Roberts, Alan Dale as Caleb Nichol, Autumn Reeser as Taylor Townsend, and Willa Holland as Kaitlin Cooper.

Summer is a popular socialite, who is Marissa’s best friend and Seth’s crush.

She was only supposed to appear in a few episodes, but became a fan-favorite and wound up becoming a regular for the rest of the series.

Summer is an animal activist and was more intelligent than everyone thought, getting accepted to Brown University.
