Twenty-year-old Ethan Jones has a secret that even his parents and foraging companions don't know - he's a mutant. And if he's found out, he'll be dragged away by the town's paramilitary Custodians to be dissected like a science project. The dull drudgery of Ethan's life is shattered when he rescues a mysterious Japanese girl from Skel savages while out foraging in the post-apocalyptic ruins of 2122AD Melbourne. When he takes the girl back to Newhome, she breaks the town's rigid conventions in her attempts to get to know him, risking the dire wrath of the Custodians. Meanwhile, the Skel are ramping up their attacks on Newhome's foraging teams and infesting Melbourne's ruins in ever-greater numbers. Is this part of a larger plan that could spell the town's doom?
