As tensions mount between the school and the people in the nearby town, a mysterious explosion at the school knocks their television station off the air. The governor calls a state of emergency and mobilizes the National Guard, and a curfew is established in town. The students respond by holding a parade in the town in violation of the curfew. On the way back to the school, their bus breaks down and local townspeople confront the students and threaten to set their bus on fire.
