Philip Malloy, a ninth-grader at Harrison High School, is in Bernie Lunser's homeroom class and likes it. Even though the principal, Dr. Doane, askes everyone to stand at "respectful, silent attention", the homeroom teacher leads out by NOT doing so. But when Philip is transferred to Peg Narwin's homeroom, a serious, but fair and true literature-loving English teacher, homeroom changes drastically for both teacher and student.
Philip receives a D in English due to his neglect and hatred for the subject and the teacher. He thought nothing of it until Coach Jamison won't allow him to try out for the track team because of a school rule that if a student is not receiving passing grades (at least a C-) they will not be allowed to try out for any sport.
Philip hums to the audio tape of the national anthem, as had been allowed in Mr. Lunser's class. Miss Narwin views this a disturbance and sends Philip to the vice-principal, Dr. Palleni, who tells Philip not to do it again and lets him go.
Philip goes home and tells his parents what happened and the (arguing) couple tell him to keep on "singing". It is, in their eyes, patriotic--"the way they brought him up!"
Philip hums again and the teacher again sends him to the vice-principals who sends him home with a two day suspension.
Philip's parents are outraged and go to a runner of the school board ellection for help--they know Ted Griffen won't miss a chance to serve his own ends. And they're right. Soon a newspaper reporter shows up and gets only half the story, printing a one-sided article that hurts one of the school's best teachers.
Philip receives all kinds of mail, praising the "patriotic" boy, from all over the country. Miss Narwin recieves hate-mail, and eventually resigns. Philip is transferred to a different school because he can't stand all the classmates' smart remarks about how patriotic he is and calling him the Uncle Sam of the school. He uses the money from his college fund and goes to a private school with no track team. When asked if he would like to lead the class in singing the national anthem, he answers, "I don't know the words."
