A 200-mile trek through Nepal, from the foothills of the Himalayas, along the world's deepest valley and into snowswept passes to the borders of Tibet, across some of the most beautiful and dramatic scenery in the world. This is a journey made by a group of inexperienced Australians of all ages who have chosen this tough trek instead of a package tour for their holiday. The film shows how much a group of 'amateurs' can undertake under the right leadership - and survive.
'There's a lot of apprehension in people about mountains, whether they're dangerous and whether they can make such a trip,' says Warwick Deacock, a retired British Major who leads the expedition. The remarkable thing about this trek is that none of the walkers has had any experience of mountains before and, 'indeed the strongest, fittest guys who have spent their lives conquering alps can come unstuck at 16,000 feet, and dear ladies of 62 who have spent the whole year as librarians go pottering along in their sun-hats with no trouble at all.'

On Thursday, 31 July 1919, nearly one half of the Liverpool Police Force - the Merseyside 'Scuffers' - went on strike. For two nights over the August Bank Holiday, Liverpool City Centre was virtually without a police force. The mob left the slums and set out on a looting spree. The Riot Act was read, the army sent for and a battleship and two destroyers despatched to the Mersey.
Liverpool men and women, who were children in 1919, still remember that weekend, and some of the police strikers recall the strike - and after.
