The film starts in the drawing office of Pegson Limited and we also see stills of the Coalville works. In the foundry we see moulds for quarry plant machinery being constructed. The core of the mould and its cap are lowered into place then molten steel is poured in. Next in the heavy machine shop we see the various methods of finishing the parts using boring mills, centre lathes and grinders. We then see activities in the erection shop and the testing area where the firm's rock crushing equipment including jaw crushers and scalping screens are put through their paces.
To see the equipment in action we then move to Uganda where Pegson Limited have supplied rock crushing equipment to provide aggregate for concrete production on the site of the Owen Falls dam on Lake Victoria. To set the scene there are shots of agriculture in Uganda (coffee and cotton harvest), a local market, men dancing and views of Lake Victoria and the River Nile.
Quarried stone is dropped into a Pegson gyratory crusher and the firm's grading screens are used to produce the required size of aggregate. We also see the local workforce hand shovelling sand which is another component of the concrete. The sand is transported by barge across Lake Victoria to Jinja. A Ruston diesel locomotive pulls the wagons containing the concrete to the construction site.
