A fearless, globe-trotting, terrorist-battling secret agent has his life turned upside down when he discovers his wife might be having an affair with a used car salesman while terrorists smuggle nuclear war heads into the United States.

In the mid-1980s, the U.S. is poised on the brink of nuclear war. This shadow looms over the residents of a small town in Kansas as they continue their daily lives. Dr. Russell Oakes maintains his busy schedule at the hospital, Denise Dahlberg prepares for her upcoming wedding, and Stephen Klein is deep in his graduate studies. When the unthinkable happens and the bombs come down, the town's residents are thrust into the horrors of nuclear winter.

The documentary recounts the world's first nuclear attack and examines the alarming repercussions. Covering a three-week period from the Trinity test to the atomic bombing of Hiroshima, the program chronicles America's political gamble and the planning for the momentous event. Archival film, dramatizations, and special effects feature what occurred aboard the Enola Gay (the aircraft that dropped the bomb) and inside the exploding bomb.

Documentary warning of the "menacing shadow" of the atomic bomb.
