Jerome lives alone. All six of the survivors live alone and isolated, never seeing another human being in the flesh - not since the catastrophic event that left the world outside an uninhabitable wilderness. Only killer cockroaches live outside and acid rain melts anyone who dares to venture out of their apartment.
The survivors are used to this life - it's all they've ever known.
But a noise in Jerome's kitchen is about to turn his world upside down, and everything he knows to be true will be rocked by a reality he never knew existed.
