Joshua Connor (Russell Crowe) is a
dowser, a man who can find water
in the Australian desert — a talent he will later employ when he goes searching for the bodies of his three sons, all lost on the same day
in the disastrous World War I battle of Gallipoli.
(E.g., dowsing could be tested by having
dowsers attempt to locate underground pipes on multiple, undisclosed -
in - advance campuses.)
