In 1978, the inhabitants of a small village in Iran called Zalava claim there is a demon among them. Massoud, a young gendarmerie sergeant, who investigates this claim encounters an exorcist attempting to rid the village of the demon. When he arrests the exorcist on charges of fraud, the villagers fear and anger escalates. Massoud and his love interest, a government doctor, soon find themselves trapped in a cursed house, surrounded by villagers who believe they are both possessed by the demon.
A hospitalized, critically ill physicist, working on a theory about black holes and the end of the world, meets a rather eccentric hospital housekeeper named TiTi. Though single, TiTi is acting as a surrogate mother for an infertile couple in order to serve humanity and raise money to build a small room of her own. When the physicist falls into a deep coma, TiTi, raised by Iranian gypsies and possessing supernatural powers, performs a strange ritual to save him. This is the start of an odyssey; an odyssey that changes their lives forever.
