Lucas (Chad Michael Murray) and Nathan (James Lafferty) spent last year learning to co-exist as estranged brothers, rivals, and teammates. Nathan watched his parents' marriage dissolve and shocked the town by tying the knot with Haley (Bethany Joy Lenz), Lucas' closest confidant.

Former best friends Peyton (Hilarie Burton) and Brooke (Sophia Bush) hope to mend their fractured relationship, while Lucas' mother must choose between her feelings for his uncle and Peyton's father. Uncertainty lingers, and the web of entanglements will only continue to thicken this season as new characters are introduced and more secrets are uncovered.  (TV Tome)
