James (Cuba Gooding Jr.), who has congenital mental retardation, has been the object of ridicule since childhood. Because he always carries a radio, "radio" has become his code name. When he is free, James likes to stay in the Hannah High School Stadium. Over time, a coach named Harold (Ed Harris) noticed him. After being teased again, Harold helped James out. Not only that, he also announced in public that from now on, James will be a member of his football team. Harold's decision puzzled the players, but soon they discovered the shining humanity of James. Under the influence of James' optimism, the team has won many battles, and the relationship between the players has become closer. James has not only walked out of the gray area in his life, but also brought happiness and hope to more people.
