River Thames, between Henley and Maidenhead, Oxfordshire/ Berkshire.
As part of an army exercise soldiers construct a bridge to cross Thames. Various shots of military vehicles driving through mud.
The soldiers, watched by their officers, float massive pontoons on river. The pontoons are joined to form half a bridge. A tractor is driven onto it. The pontoons then drift down river and are connected to another half of a bridge coming out from the opposite bank.
Once bridge is completed, a convoy of army vehicles drives across. Various C/Us of army officers and soldiers, including General McCleod, G.O.C in charge of Eastern Command.
