Sarah is 10 years old. She scratched her knee and developed an infection. When the infection threatened her life, her parents agreed to have her leg amputated. But the amputation didn't stop the infection.

Her family have been told she has days to live, but a scientist has offered them a glimmer of hope.

We join Sarah's imaginative world as she heads to the front line in the war between humanity and bacteria.

Oliver Emanuel's potent and playful drama set in a near-future in which doctors can no longer prescribe antibiotics.
