Earth is locked in the icy grip of a devastating nuclear winter and those who have managed to survive the radiation and deadly Ebova virus now war over dwindling resources. As well as the cannibal gangs and doomsday cults, there are still those determined to rebuild a better world. Ingenuity, tenacity and courage are foundations for survival, but as the atmospheric dust settles, the climate becomes dangerously warm. The remnants of humanity are forced southwards to the last habitable landmass of Antarctica, origin of the drones which hunt them, and home to the mysterious Gaia.
