Among the correspondence that his secretary gives him every morning, Eloy Granero receives an envelope one day that contains a photograph. It’s an image that he recognizes perfectly, that in fact he had never been able to forget, but that crashes into the calm waters of his life, a successful and powerful life as the president of the family business that he inherited. Only Claudia, the owner of a photographic shop where Eloy has developed his films for the last twenty years, had access to this image. Only Claudia, colorless and insignificant Claudia, might have the revelation of a terrible event in her hands, and with it the key to re-establishing the story of Eloy’s life. Dark passions, perversion and helplessness, inanity and even a timid attempt at redemption, occur revealing an existence that has crossed the shadow line and to which we are drawn closer, paragraph by paragraph, by an unspeakable fascination.
