An argument between Dave and Lynsey results in a 'No Talking' contest between the boys and girls in the fifth grade of Laketon Elementary School. The teachers are fascinated by the radical transformation of the most raucous bunch of fifth-graders into a group of quiet, orderly children. The fifth-grade teachers react differently: the English teacher is fascinated, the Science teacher is annoyed, while the Gym teacher is unconcerned. One day, after a nasty argument with the principal, Dave invites the teachers to take part in a contest. Circumstances alter the equation among the girls, boys and teachers of the school forever.
