OTH is the abbreviation for One Tree Hill. It is a show on the channel the WB, which stars Chad Michael Murray, James Lafferty, Tyler Hilton, Bethany Joy Lenz, Sophia Bush, Hilarie Burton, and more. It's basically about two boys in high school who find out they are brothers. One of the brothers is popular, while the other is a "loser." But, they resolve their differences and form a sort of alliance against their father, Dan. It has alot of drama that relates to teenage life such as drugs, alcohol, boyfriend/girlfriend drama, death, teachers, etc. GREAT SHOW, highly recommended.
