West German soil resounds again to the tread of marching feet and the rumble of armored vehicles--but this time for the preservation of peace. The film presents an eye-witness account of training activities of the Royal Canadian 27th Infantry Brigade stationed at Hanover--Canada's forceful contribution to NATO ground forces for the defense of Western Europe. A sight-seeing tour of German countryside, an intense mock ground attack, and a military parade on Hanover's public square are the main features. Everywhere in the background is the mute eloquence of the last defeated aggression.

Since the first film was made explaining the power of the atom, nuclear technology has made great advances. This film is an up-to-date account of the many areas of nuclear research and recent developments in Canada. It was filmed at the long-functioning atomic reactors at Chalk River and Rolphton, and at the latest and largest atomic power station at Pickering, as well as at laboratories across the land where experimentation is carried out in both pure and applied nuclear science. Produced for the NFB by Crawley Films Ltd. for Atomic Energy of Canada Limited.
