John O'Connor and Jim Rollins, rival ranchmen, each has a baseball team, though Rollins' usually wins because O'Connor's foreman and pitcher, Bide Goodrich, is paid by Rollins to throw the game. When Tom Hanley and his grandmother settle on O'Connor's ranch, the boss discovers that he is a good pitcher; and Rollins, who has bet heavily on the Fourth of July game, plots to eliminate Tom.
