Sudden, destructive blasts. Innocent victims. Can science help stop the epidemic of brutal bombings across America? The Unabomber. Oklahoma City. The World Trade Center. Abortion clinics. Bombing is on the rise in this country. A deadly and anonymous crime, bombs are indiscriminate, often killing or maiming innocent bystanders. Join the hunt for the bombers that are terrorizing the country. Follow the investigators on the trail of the bombers and see what it takes to crack a bombing case. Bombs are relatively easy- if extremely dangerous- to create, and leave precious few clues about who is responsible. But sometimes the smallest fragment of evidence of a psychological profile can be the key to stopping these terrorists. To show what science can do to help, NOVA profiles several notorious bombing incidents. Get an inside look at the celebrated case of the Unabomber, the World Trade Center, and lesser known cases like the Army of God, the rash of bombings in the Southeast in 1989, and even the tragic story of a booby-trapped toothpaste container placed by a teenager that cost a 5 year old girl her arm.
