Thirteen-year-old Charles Blandin has a burning desire to be a big league pitcher when he grows up, He knows he needs coaching to help him pursue his goal. His father, who runs the local chapter of the Ku Klux Klan in their small Virginia town, has neither the time nor the inclination. So Charles decides to seek tips from a forbidden source - a former semipro pitcher who also happens to be the father of his Negro friend Otis. The two boys had stumbled into an unlikely friendship two years before, one that centered on their common love for baseball - until Charles' father had gotten wind of it and brought it to an end. Charles has always accepted white society's belief that Negroes are inferior, but in his mind Otis and his parents belong in a separate category. So he secretly ventures to their house, rekindles his friendship with Otis and gets helpful tips from Mr. Osgood. But in time Charles' father hears about the pitching lessons and orchestrates a scheme that brings the sessions to a violent end - leaving both boys scarred in the process. Charles and Otis go their separate ways, but both boys pour themselves ever more deeply into baseball. Years later they both reach the professional ranks in Washington, D.C. - Charles as a pitcher for the Washington Senators and Otis as an outfielder for the Washington Black Diamonds of the Negro National League. They have a chance encounter outside Washington's Griffith Stadium, and at first they are happy to see each other. But friction quickly develops because both of them have become saddled with racial bias and can no longer see past the other's skin color. Eventually they have a bitter falling out. They end up squaring off in a season-ending exhibition game, with life-altering results.
