Imagine the future - a strange new weapon is detonated high over a large city. There is no explosion, no visible destruction, but everything electronic within the range of this weapon will go out.. permanently. Every electronic gadget in every home and office - disabled. No computers, no TV, no life support systems in hospitals, no water supply, no heat, no lights - truly, a return to the dark ages. Imagine a full range of new weapons; one can take out the electricity in your city, another can destroy you. If you haven't heard about these weapons, it's no surprise. Their development has been secretive and they sound more like science fiction than reality. When did this reality really begin and how far advanced is it now? This revealing documentary opens the window on this - until now - secretive science.
