A military exchange between New Zealand and the United Kingdom is the focus of this National Film Unit short. About 150 Kiwi soldiers head to London for Exercise Powderhorn in 1964, which includes guard duty at Buckingham Palace and the Tower of London. And they still have time to see the sights. Meanwhile a contingent from the Loyal Regiment in North Lancashire arrives in New Zealand for Exercise Te Rauparaha. They experience jungle warfare in a mock battle on the West Coast and practise mountain craft in the Southern Alps.
