A two-part series exploring, celebrating and respecting the myriad lives that live upon us and in us, some waging war against us, others living alongside, and some that we can't live without. Wildlife Biologist and Presenter Lizzie Daly introduces us to Welsh microbiologists, some leading the world in fields of research, giving us tales of the uninvited. Episode one looks at the good and the bad in the world of bacteria.
