Building is Howard's passion, and he is so absorbed in his plans to build an elaborate resort in the Blue Mountains of Australia that he ignores certain obvious signals that his business partner is not entirely on the up-and-up. After a brush fire destroys the resort, an insurance investigator comes nosing around, whom Howard's partner deals with in a drastic manner. By the time Lloyds of London's senior investigator George Engels (James Mason in one of his last roles) arrives on the scene, Howard (Tom Skerritt) is anxious to set things to rights.

As World War I rages, brave and youthful Australians Archy and Frank—both agile runners—become friends and enlist in the Australian and New Zealand Army Corps together. They later find themselves part of the Dardanelles Campaign on the Gallipoli peninsula, a brutal eight-month conflict which pit the British and their allies against the Ottoman Empire and left over 500,000 men dead.
