A World Without Microbes dives into the fascinating world of the infinitesimally small. Thanks to a rigorous investigation with the help of specialists, beautiful CGI and astonishing microscopic images, we discover to what extent the minute beings surrounding us and living inside us are the masters of life on earth.
