In the last 50 years, the spectacular increase in the number of cases of allergies and asthma is mobilising many scientists around the world.
Through interviews with leading researchers across the globe, this documentary reveals the main reason is the lack of diversity of microbes in our increasingly germ-free environment, and it explains the beneficial role of microbes for our immune system, particularly for the youngest. It also longs for renewing our contact with the natural world.
