Brian Stead is the only man who would dare ask Peter Thornton to travel direct from Alaska to Western Australia - a temperature change of 134 degrees! What is more, Stead is the only man Thornton would do it for. Thornton questions his loyalty, though, when he is lost in the outback without radio or salt tablets. Struggling to survive he wonders whether Mogul's demands are too great...

There is plenty of genuine Down Under in this episode. Ray Barrett is joined by fellow Australians Kit Taylor (Raven) and Peter Bathurst (Harris), and by Denis Quilley (Whitmore) who has just returned to Britain after a highly successful spell in Sydney. Director Ken Hannam is another recent import from Australia.
Kit Taylor has worked in the exact part of the outback where this story is set, and bears witness to the problems of survival there - salt tablets and all.
