In a desperate bid to preserve humanity and ease population burdens on Earth, the UN has initiated a "draft" for colonizing the nearby planets, where conditions are so horrific and primitive that the unwilling colonists have fallen prey to a form of escapism involving the use of an illegal drug (CAN-D) in concert with "layouts". Layouts are physical props intended to simulate a sort of alternate reality where life is easier than either the grim existence of the colonist in their marginal off-world colonies, or even Earth, where global warming has progressed to the point that Antarctica is prime vacation resort territory. The illegal drug CAN-D allows people to "share" their experience of the "Perky Pat" (the name of the main female character in the simulated world) layouts. This "sharing" has caused a pseudo-religious cult or series of cults to grow up around the layouts and the use of the drug.
