The show is set in the fictional town of Tree Hill in North Carolina and initially follows the lives of two half-brothers, Lucas Scott Chad Michael Murray and Nathan Scott James Lafferty , who compete for positions on their school's basketball team, and the drama that ensues from the brothers' romances.

With the beginning of the fifth season, Schwahn advanced the timeline by four years to show their lives after college, and he made it jump a further fourteen months from the end of the sixth to the start of the seventh season.
