Beautiful countryside of the Trossachs and Loch Katrine, Glasgow's water supply.
Titles read: "Just a drink - of water! A Glasgow Cameo".
Brief shots of children and men drinking from water fountains in streets of Glasgow. We then see several shots of the beautiful countryside, mountains and lochs in the area of the Trossachs. Water flows from Loch Katrine into the reservoir at Milguy, to be used by the people of Glasgow.
