Division brought war between humans; division made them fight with the forbidden weapons. And so Earth was contaminated and frozen. The few survivors hid underground. After 30 years, they still hope to return home, waiting on shelters called "Babyls". We follow the lives of a group of friends in the shelter "Babyl 137" while they try to entertain themselves and from time to time, sneak into the restricted areas to scout memories of the lost civilization.
