Film showing the food contributions supplied to Britain by various colonies and dominions.

Although more land has been given over to food production, a significant contribution is made by the British Commonwealth of Nations. The sources of items in a shopping bag are described by people from the countries involved: lamb, sultanas, wheat and fruit from Australia, New Zealand butter and cheese (90% of produce going to UK), West African cocoa and cocoa butter, vegetable oil from the Gold Coast, tea from Ceylon. Distribution of these items when in Britain is handled by 19 Divisional Food Offices which coordinate the movement and storage of the foodstuffs, and redirect supplies in times of emergencies. The link between producers and suppliers is sea power - tribute is paid to the convoys. This chain of production, distribution and sales culminates in the food being served in ordinary British households.
