The Last Leaf

When a brilliant young scientist at the U.S. Biological Warfare Laboratories in Maryland discovers a new anthrax-like strain of bacteria he recognizes unique features that can change the world. Dr. Chris Gregory perfects the organism (BT-2000) to selectively destroy tobacco plants. He and seven other scientists (code name: Poker Players) devise an illegal covert operation. After smuggling BT-2000 into key countries they use top-secret devices stolen from Ft. Detrick to dispense the bacteria worldwide. Tobacco is soon eradicated from the earth.
