‘R.W. Collins', a famous hijacker who escaped by parachuting out of a plane with his money five years ago is found dead, hanging from a tree in the National Park he bailed out over. He died before he hit the ground and has been hanging there, undiscovered, for 5 years now. Quincy and Sam are sent to the scene to see if they can find out whom the man really was. When they reach the park they find that things are a lot worse than they could have imagined, the anthrax particles he used to hijack the plane were released when the body was found and are spreading throughout the area infecting people who come into contact with it.
