When an overlooked case of immunity is uncovered decades after a pandemic took Humanity to the brink, a doctor leads her team into unknown territory to find a survivor who may no longer even be alive.
For decades, the world has faced a frightening brain-wasting disease that includes some exceedingly anti-social symptoms!
Yet, survivors in an outpost in Australia uncover a nugget of hope: An obscurely-labelled, desiccated fragment from a compulsory bio-sample collection done in the early days of the plague. It suggests someone had faced the disease and fought it off through immunity!
With time and resources at their lowest ebb, Dr. Rachel Morrison must lead a team into the wilderness to retrieve the unknown donor who hopefully has beaten fate by surviving for 25 years among the contaminated "Mealy-Mouths".
A man or woman. Alive or dead. Who may have moved away long ago. A needle in a haystack. A dangerous haystack.
