The fires of war become the forges of Australian invention. William Scurry invented a decoy Drip Rifle to help Anzacs safely evacuate from Gallipoli. Alexander Worsfold built his all-terrain Transporter to hurry injured soldiers to field hospitals on the Western Front. Adelaide-born Howard Florey and his team developed the wonder drug Penicillin that was first deployed amongst infected allied soldiers during World War Two. And from Wollongong, Evelyn Owen's Sub Machine Gun out-performed its competitors and become known as ‘the diggers' darling'.

Four great medicos and mavericks risked their careers testing these ground-breaking medical inventions. Psychiatrist Dr Joh Cade discovered the psychological effects of Lithium on his bipolar patients after first testing its toxicity on himself. Dr Mark Lidwill worked in secrecy on the world's first Pacemaker following his experiments on the hearts of recently deceased patients. Prof Fiona Wood developed a process to help severe burns victims recover quickly with Spray On Skin, and the Ansells helped fight infection with their Disposable Medical Gloves.
