Over a grainy black and white film, a voice informs you what to do if there is the flash of the atomic bomb. Duck and Cover. The film ends and a teacher tells her class that was an important film made by the government and that there will be a test later. The teacher, Edith Harcourt, asks her class what the first thing to do in the event of an atomic attack is, to which a voice calls out drop dead. Enraged, Edith demands who asked that and a kid, Tommy says how they would all just die. Another kid, Stevie, gets in a fight with him and Edith goes from anger to paranoia as she has never lost control of a class. Then a voice tells Edith that this isn't right and that it will help her.
