This compelling biography (written by Australian historian Kristen Alexander) charts the extraordinary journey of Clive Robertson Caldwell, Australia's highest-scoring fighter ace of the Second World War. From his early frustrations in the North African desert to pioneering combat tactics like "shadow shooting," Caldwell became a feared and respected leader. His aggressive fighting style and quick thinking earned him the nickname “Killer” and helped him down enemy aircraft in both the European and Pacific theatres — a rare feat among Allied pilots. With 27½ confirmed victories, Caldwell’s wartime record was unmatched by any other Australian. This documentary follows his rise through the ranks, his legendary engagements over Tobruk and Darwin, his leadership of 1 Fighter Wing, and his later controversies. A story of courage, innovation, and resilience in the skies of WWII.
