It's senior year on season three of One Tree Hill. Dan tries to track down who almost killed him, Haley fights to save her marriage, Peyton comes to terms with her birth mother, Brooke creates a hot clothing line, and Keith comes home. Tragedy also strikes Tree Hill High, and suddenly who wins the cheerleading tournament or basketball championship seems insignificant compared to who lives and who doesn't. Also on DVD: season one of Whose Line Is It Anyway and the complete series of The Book of Daniel.
