The fifth season of One Tree Hill makes TV history, jumping ahead four years in the lives of its characters. Season 4 ended with the young characters graduating from high school, and Season 5 begins, post-college, four years later. Some of the characters have found success while others have failed. Some are the same, and some are very different. And while their storylines will actively move forward, the show will also dip into the past, returning to incidents and events of the last four years, sometimes for a moment or a scene, other times for an entire episode.
