This is a rather picturesque but dry documentary about the construction of a generator in the Canadian wilderness that will augment three others buried deep inside the mountains and support the country's burgeoning aluminium industry. The plentiful aerial photography is impressive - of the natural features, the astonishing power lines that span this most hostile of terrains, and of the almost unnoticeable constructions that stretch some ¼ miles under the rock. The narration comes from the enthusiastic project manager - who likes superlatives, lists and big numbers! Everything about this project is grand scale and though we see nothing really of the construction and there's probably just a bit too much air travel, it's still quite an interesting illustration of just what man and engineering can achieve.
