When Crospinal's ailing father finally dies, he is left utterly alone in the pen, surrounded by encroaching darkness. The machines that tended to him as a child have long ago vanished, and the apparitions that kept Crospinal company are now silenced. Struggling with congenital issues, outfitted in a threadbare uniform, he has little choice but to leave what was once his home, soon discovering that nothing in the outside world is how he had been told it would be. In his quest for meaning and understanding, and the contact of another, Crospinal learns truths about himself, about his father, and about the last bastion of humanity, trapped with him at the end of time.
