Coach Joe Newton has used the sport of Cross Country Running to teach simple but important lessons to high school boys for the last 50 years. "Always do your best", "be on time" and "it's nice to be great but far greater to be nice" are mantras, which have turned the Boys Cross Country team at the public York High School in Elmhurst Illinois into the most winning high school team in any sport in America. Along with mastery of their sport, Newton turns boys into men, who carry his teaching and his love for each of them throughout their lives. The Long Green Line documents the York Duke's 2005 Cross Country season as the runners seek their record 25th state title in 50 years.
