"Crossing the Line" is the tragic yet uplifting story of athletics prodigy Danny Harris, and his battles with his demons on and off the track. Orphaned at 14, Olympic hurdler at 18, crack cocaine addict at 22, world number one at 25, and finished at 30, this documentary explores the fine line between greatness and addiction. Featuring some of the biggest names in track and field history including Carl Lewis, Edwin Moses and Jackie Joyner-Kersee, and shot by the team behind HBO's Emmy Award-winning Sound City and Sonic Highways, the dramatic tale of Harris's rise, fall and eventual redemption is like no other.
