Gossip buzzes like a swarm of bees on the first day back at Harbor High School. Thanks largely to his vindictive rival Luke (Chris Carmack), new student Ryan (Ben McKenzie) feels like the proverbial square peg in a round hole. Ultimately, Marissa (Mischa Barton) is forced to choose between Ryan and Luke, and her decision may spark yet another punch-fest. Meanwhile, Summer (Rachel Bilson) feigns indifference to Seth (Adam Brody), and as a consequence may lose him to Anna (Samaire Armstrong). And outside the walls of the school, Sandy's (Peter Gallagher) newest legal case threatens to cause friction between his wife, Kirsten (Kelly Rowan), and her father, Caleb.
