“The Blind Side” depicts the remarkable true story of Michael Oher (Quinton Aaron), a homeless African-American youngster, who is taken in by the Touhys (Sandra Bullock and Tim McGraw), a well-to-do white family who help him fulfill his potential. At the same time, Oher’s presence in the Touhys’ lives leads them to some insightful self-discoveries of their own. Living in his new environment, the teen faces a completely different set of challenges to overcome. As a football player and student, Oher works hard and, with the help of his coaches and adopted family, becomes an All-American offensive left tackle.
