In this film, the need for civil defense against atomic and thermonuclear attack is presented over footage of citizens engaging in various evacuation, rescue, and civil defense activities during a large-scale air raid drill. The civil defense emergency broadcasting system is explained. As part of the national civil defense plan, a number of structures--homes, buildings, railroads, forests, automobiles, etc., are set up in the Nevada desert. The military, civil defense planners, scientists, and the news media gather at News Knob to observe the blast. Soldiers are dug into trenches only a few miles from ground zero. A bomb is dropped on the ground zero target. Cameras and other instruments record its effects onthe structures at the bomb site and also on the men in the trenches, some of whom are standing and facing the blast. Immediately after the explosion, the soldiers march toward ground zero, monitoring the amount of radiation present as they go. Shots include: a local civil defense headquarters; Japanese ruins after an atomic explosion; atomic test on a Pacific atoll; ground level and aerial views of the bomb damage in Nevada.
