The world outside has grown toxic, the view of it limited, talk of it forbidden. The remnants of humanity live underground in a single silo. But there are always those who hope, who dream. These are the dangerous people, the residents who infect others with their optimism. Their punishment is simple. They are given the very thing they want: They are allowed to go outside.

A simple pill, it had been discovered, could wipe out the memory of any traumatic event. At almost the same moment in humanity’s broad history, mankind discovered the means for bringing about its utter downfall. And the ability to forget it ever happened.
