This film deals straightforwardly with the consequences of a nuclear attack for the Canadian Prairies. The Prairies are singled out because of their proximity to huge stockpiles of intercontinental ballistic missiles located in North Dakota. Scenes include a visit to a missile base and to an emergency government bunker in Manitoba. A doctor, a farmer and a civil defence coordinator provide different perspectives on nuclear war. Although the film focuses on one region, it provides a model for people everywhere who would like to know more about their own situation but don't know what questions to ask.
