John and Sam travel to Greenberg, where they discover and investigate an abandoned human factory. Potcrock Isle's mayor, Mayor Hoffman, learns about Sam's altercation at school and her attempt to go outside and consequently banishes the duo from the settlement and sends them on a train called 'Charon' to the outside world. During her adventures with John, Sam is followed and provoked by an identical incarnation of her called 'Mother'. One day, Sam receives an opportunity to attend school but is expelled following an altercation between her and three of her classmates. Despite the village's teachings and the MIASMA's presence overground, Sam still wishes to see the outside world. Both live in a subterranean society called Potcrock Isle, whose inhabitants are taught to fear the outside world. In the near-future, a toxic plague called "the MIASMA" has spread worldwide, destroying societies and devouring everything in its path, consequently forcing survivors, including a miner named John and a girl named Sam, to restart life underground.
