Undefeated is an Oscar-nominated documentary that follows the underrated football team from Manassas High School -- a lower-income school in North Memphis, Tenn. -- through a year of tragedies and triumphs. Led by Bill Courtney, a businessman who volunteers his time to coach and mentor the mostly fatherless young men on the team, the Manassas Tigers fight their way to an extraordinary season. The action follows Coach Bill and three of his defensive linemen: OC Brown, a gifted left tackle who needs serious academic help to qualify for a scholarship; Chavis Daniels, a short-fused linebacker with rage issues; and Montrail \"Money\" Brown, a scholar athlete whose prospects plunge after an injury.
