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.
Unfortunately the movie A Dangerous Summer is not yet available on HBO Max.
