After a nuclear outbreak that nearly wiped out the human race, a community was built to keep its citizens safe and sound from the barren and plagued land outside. In this community, named Hobwin, those who came of age each year were required to undergo an Operation that would replace most of their human body with a robotic one. However, eighteen-year-old Grey Lester wanted otherwise. His family and friends often shunned him for his unpopular opinion on what it meant to be human, but he always kept his word. So when it was time for the Operations of his batch, what happens when he uncovers a dark and long-hidden secret that could change his and his friends' lives forever?
