It is about the noisy fifth grade boys of Laketon Elementary School who challenge the equally loud fifth-grade girls to a "no talking" contest. This competition turns out to be really hard. Main themes are related to Gandhi's practice of maintaining silence one day a week, accommodations made in school for an especially loud and talkative fifth-grade group of students, gender dynamics (in elementary school), and the civil disobedience those students find themselves practicing when their "right to remain silent" is questioned by the school's teachers. The contest goes on and on until they meet on decision.
