An evangelist whose church is being investigated by the government is found dead in a motel room., drugs and alcohol at his bedside table. Quincy is told to come up with the mode of death quickly, everyone wants to know how, and why, he died. The scientific results are borderline so Quincy asks Asten to authorize a psychological autopsy.

‘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.

Quincy and Sam are called to a prison to help investigate the murder of one of the inmates. Once there they soon find themselves held hostage by the prisoners when they begin a riot.
