Since his mother started chemotherapy, the teenager Connor has had nightmares every night. In his dreams, there is always dark and gloomy weather, strong winds, screams and hands that cannot be clenched no matter how hard he tries. He always has nightmares with the same content, until one day an uninvited guest appears at home. The demon with an ancient breath tells Connor that it was summoned by him, and it wants to exchange three stories for Connor's own real story. Connor is not afraid of demons, because what he is facing is that his beloved mother is dying step by step, which is a more terrifying thing. The night makes Connor feel weird, and his daytime life is also very difficult. Connor's father left them, and the grandmother who came to take care of their lives did not get along well with Connor. In addition, he must endure those bleak days in school-the exaggerated sympathy of teachers and the bullying of classmates. Gradually, Connor discovered that there is a certain pattern in the time when the demon appears every night, and the meaningless stories it tells seem to be metaphors for something. Is it the messenger of death, or the miracle that Connor expects to appear? The story of Connor's reluctance to confront the devil is actually the darkest secret in his heart...
