Red double-decker buses are one of the main features of the streets of London, but to the citizens of continental Europe, accustomed to single-deckers, London's R T buses are Leviathans. It was as an appropriate symbol of Britain that London Transport sent two of its newest buses to accompany the Made In England Exhibition which toured Switzerland, Germany, Denmark and Sweden. The film follows the buses through Zürich, Heidelberg, Hamburg, Copenhagen and Malmö, and shows some of the incidents which the London drivers will remember from their crowded goodwill tour.
