When Brooke takes Owen to New York for a glimpse of her other life, she's faced with a ghost from her past. Haley reels from a devastating blow to her marriage, while Nathan and Lucas muster their courage to attend Dan's parole hearing. A major record label takes an interest in Peyton's recording artist.

On the very special 100th episode of "One Tree Hill," it's Lucas and Lindsey's wedding day and Peyton must choose whether to intervene or lose her true love forever. Nathan uses the occasion to attempt a reconciliation with Haley, and the recently paroled Dan shows up for the family reunion.
