The true story of penicillin - the unlikely and chaotic tale of Australian Howard Florey and how the most important medical drug in the world was made from mouldy fruit.
As Hitlerâ€™s armies invade Europe and the value of human life diminishes, a small team of scientists at Oxford University make one of the greatest discoveries in the history of medicine.
As news of their funny yellow powder leaks out to the press, wartime Britain looked for a hero. Instead of Florey and the Oxford team, newspaper magnate Lord Beaverbrook chose Scottish scientist Alexander Fleming, who had first noticed the penicillium effect 14 years earlier - and discarded it.
How story of how penicillin was invented is a fascinating tale of wartime scarcity, personal conflicts, and a sobering lesson in the damage done to truth by wartime propaganda.
