Hope's last stand: A hellish apocalypse reduces the human population to numbers so low, future generations will inbreed and degenerate. Survivors turn to Hell's Gate, an experimental sedation prison, to secure more females for world repopulation. They must depend on a damaged psychologist, Jason Adams, to select which female inmates to revive. While searching the prison, an accident revives a serial killer and inmates take over the asylum. Adams must use his heart and not his head to save the woman he loves and save the world from a mad man.
