Nathan's Uncle Cooper (MICHAEL TRUCCO - "Pensacola: Wings of Gold") visits Tree Hill to take Nathan and Lucas on an auto racing trip. On the track, Nathan and Lucas are challenged to a contest by beautiful Daytona (SCHUYLER FISK - "Orange County") and her obnoxious brother Garrett (STUART LAFFERTY, series star JAMES LAFFERTY's real-life brother), but things go horribly wrong when Nathan loses control of his car and crashes into a wall. Meanwhile, Deb's addiction to pain pills intensifies, and Dan exposes Andy's (recurring guest star KIEREN HUTCHISON) relationship with Karen to Andy's class.

It's been four years since the gang left Tree Hill, and many things have changed. Lucas (series star CHAD MURRAY) has published his first novel, ""An Unkindness of Ravens,"" and now works on his second. Along with Skills (series star ANTWON TANNER), Lucas also coaches his former high school basketball team, vowing to take the squad to another championship. Peyton (series star HILARIE BURTON), who is at the beginning of a budding music venture, loved two things when she graduated from high school: Lucas and music. But did leaving Tree Hill for an internship at a record company in Los Angeles change her mind about either passion? Peyton's best friend Brooke (series star SOPHIA BUSH) has been chasing her dream of becoming a top fashion designer with her clothing line Clothes over Bros. Four years later, Brooke finds herself at a crossroads; she has found some success, but at what cost? Nathan (series star JAMES LAFFERTY) and Haley (series star BETHANY JOY GALEOTTI), young parents who are trying to find their way

After a particularly spectacular basketball game, Lucas quickly supplants Nathan as the team's most popular player.

Unable to cope with the pressure from Dan, Nathan quits the basketball team.
