At the same time, the film tells the stories of three patients, in the USA and China, who suffer from life-threatening diseases triggered by microbial loss and are trying experimental treatments that hold hope. As theCovid-19 pandemic hits, Marty pivots to focus on how our microbes may help protect us from the virus and future pandemics, while Gloria spearheads the creation of an international microbe vault to safeguard precious specimens.
Our microbes are vanishing rapidly and life-threatening diseases are skyrocketing. But what makes these ‘good germs’ so important?

Over the last seventy years we’ve lost half of our microbial diversity at the same time we’ve seen stratospheric increases in deadly diseases like asthma, food allergies, obesity, and diabetes. Is the destruction of our microbiome making us sick?
