This story is divided in three chapters. 1) "The Visitor": The drifter writer Tran Thanh Loc arrives in an old house and is lodged by the gorgeous Hoa. Along the days, he falls in love for her and discloses the truth about the hostess. 2) "Only Child": Loc is sick, totally disconnected of the world, but his nurse Linh heals him. He writes the best-seller The Visitor about his relationship with Hoa and becomes a successful writer. He proposes and marries Linh, but when he decides to have a baby, Linh is haunted by her hidden obscure past. 3) "The Diviner": Linh's parents send the fraudulent diviner Lan to use her pretentious knowledge of Feng Shui to help Loc, and she sees ghost in the house. Her son and aspirant writer Bao does not believe on his mother until he finds a surprising secret about Loc.

Récemment divorcé, Greg, dont la vie va à vau-l'eau, rencontre la délicieuse Isabel, une femme vivant dans la rue, convaincue que le monde, brisé et pollué autour d'eux, n'est pas réel. Elle est persuadée qu'ils vivent dans une simulation, laide et rude, à l'intérieur d'un autre vrai monde, beau et en paix. D'abord sceptique, Greg finit par découvrir qu'il y a peut-être une part de vrai dans la théorie du complot d'Isabel.
