Scouting through the parts of the city damaged by the recent storm, McKay and his team of scientists pick up a distress call - two of the team who were checking a different part of the city are being attacked by some unknown menace. They hurry to help, finding one scientist dead and the other sobbing. As the rest of the team look on in horror, the second scientist jumps up, struggles violently against terrifying hallucinations, and then she too drops dead, bleeding from the nose.
