A group of Australian officials are investigating a reported discovery of wolframite, a strategic material needed for the manufacture of munitions. The rich mineral is found in central Australia on land owned by Frederick Jamieson, a rich businessman. They also realize that German agent, Mark Heinrich is behind an attempt to steal the war matérial. When an aircraft flown by Jamieson's pilot, Jerry Marsden, is sabotaged by Heinrich, the aircraft is forced down in the outback. Marsden and mechanic Monty Martin survive and encounter "Mulga" Flannigan, an old prospector who warns the pair about the dangers of the outback. The next morning, in affirmation of the lurid tales Mulga has told, another prospector staggers into their improvised campsite, with a spear wound and soon dies. Aboriginals, including Peters swoops low over the stranded fliers, but Ryan, who is working for Heinrich, flies on to Alice Springs. Ryan lies about what he had seen, telling Marion, Jamieson's daughter, who loves Marsden, that the young pilot was killed. Ryan was told to kill Marsden but tries to find a way to doublecross the enemy agent. Deciding to press his advantage, Heinrich visits Jamieson, hoping to force the businessman to surrender his claim on the wolframite mineral. The meeting devolves into violence and Jamieson is shot and killed. Marion is threatened but Ryan appears to confront him. Ultimately, Marion is rescued and Heinrich is apprehended.
Wings of Destiny was shot, in part, on location at the Sydney waterfront and featured footage of aboriginal tribal life from Kathner's earlier film,Phantom Gold. It reportedly took two years to research and six months to film at a cost of "thousands of good Australian pounds." Raymond Longford has a small role as an old bushman who rescues the party in the desert. The aircraft used in Wings of Destiny was a Ryan Brougham.
Release
Wings of Destiny was previewed to the press, after which some scenes at Alice Springs were deleted and a courtroom scene was added to the end of the film. It was passed for registration as an Australian quota production under the Film Quota Act and released in September 1940. Reviews and public reception were poor. The critic from the Sydney Morning Herald called Wings of Destiny:
... A very inferior picture... The story contains evidence and imagination, and the film has some good photography, but the camera is never allowed to roam, so that almost every interior scene is focussed on some corner of a room, and remains there until the scene ends. The exterior scenes are much better... Occasionally dramatic tension is achieved, also some good Australian characterisation.
