The refugees listen to radio and television reports of a wave of mass murder being committed across the east coast of the United States by an army of cannibalistic, reanimating corpses, and posses of armed men patrolling the countryside to kill the ghouls. They confirm that the ghouls can be stopped with a bullet or heavy blow to the head, or by being burned, as Ben discovered, and that various rescue centers are offering refuge and safety. Scientists theorize that the reanimations are occurring due to radiation from a space probe that exploded in Earth's atmosphere on the way back from Venus.
