On Tuesday, September 18, 2001, just one week after the terrorist attacks on the Twin Towers and the Pentagon, letters containing anthrax spores were received by several news media offices and Senate Majority Leader, Tom Daschle. Meanwhile, a similar letter containing anthrax addressed to Senator Patrick Leahy was misrouted and later found in a mail processing facility in Virginia.

As a result, five people died of inhalation anthrax and 16 others were sickened, the Hart Senate Office Building and other Senate facilities and several mail-processing facilities were contaminated and had to be evacuated.

This documentary tells the story of how the Environmental Protection Agency (EPA), the National Institute for Occupational Safety and Health (NIOSH), the Center for Communicable Diseases (CDC), and other federal military and civilian agencies, working under severe time pressure and in the full glare of intensive media coverage, collaborated to solve a scientific and engineering challenge never before faced — the decontamination of an entire building contaminated with deadly anthrax spores.
