Nathan Scott is Tree Hill High's biggest basketball star and is dating Peyton, a cheerleader. Nathan's half brother, Lucas, joins the team - and threatens to take both Nathan's spot in the lineup and his girl.

Lucas plays his first game as a Tree Hill Raven...and chokes. He isn't the only one confronting insecurities: Peyton can't find the courage to submit her drawings for publication.

Last year's time-capsule is maliciously opened 49 years early, revealing many kids' embarrassing secrets, lies and even worse truths, shown on TV screens at school and even on the Internet. Peyton prepares a benefit for the National Breast-cancer action, in memory of her recently deceased ma Ellie Harp; it rocks and brings most kids back together. Keith announces his engagement to Karen and his plan to adopt Lucas. Jimmy Edwards, who bagged the worst on everyone in his time-capsule speech, gets roughed up, but the Scott brothers, Mouth and Rachel save his bacon. Dan reminds Keith how close they were as boys and hands him the black ledger but is scorned and burns it. Nathan and Haley enjoy closeness again. Lucas embraces Keith as his future father, without step-.

A dangerous day at Tree Hill High gives Nathan and Lucas a common goal, as they put their lives on the line to save their friends when a distraught student comes to school with a gun and holds Haley hostage.
