Anthrax, smallpox, ebola and more-- The frightening past and lethal future of biological warfare.

In the chilling aftermath of the terrorist attacks on the World Trade Center and Pentagon, America finds itself threatened by powerful biological weapons potentially as lethal-- but more portable-- than a nuclear arsenal. NOVA follows three reporters from The New York Times as they travel the world researching biological weapons for their headline-grabbing bestseller, Germs, and for this in-depth documentary.

NOVA, along with authors Judith Miller, Stephen Engelberg and Pulitzer Prize-winner William Broad, trace the veiled history of "black biology" and discover the frightening truth about the United States’ involvement in the development of biological weapons, devastating Soviet biological stockpiles, classified government research projects and a world totally unprepared for germ warfare.

In Bioterror, bioweapons experts, former Russian military leaders, biologists, unprecedented access to biological factories, and insights from high-level military personnel answer the toughest questions: Where do germ weapons come from? Who has access to them? Can the air we breathe become a weapon? And can America defend itself against germ warfare?
