Troubled young pediatrician Francesca (a fine and appealing performance by Ana Torrent) is traumatized after losing a child to crib death. When Francesca and her family move to a new house in the country, Francesca begins to suspect that the remote abode might be harboring a few terrible secrets that push her to the brink of madness. Writer/director Elio Quiroga relates the compelling story at a gradual stately pace, maintains a grimly serious tone throughout, grounds the fantastic premise in a believable mundane reality, and ably crafts a spooky atmosphere that becomes more eerie and unsettling as the narrative unfolds towards a genuinely harrowing conclusion. Moreover, Quiroga deserves additional plaudits for the inclusion of a bold conspiracy subplot concerning the Catholic church suppressing the truth about past heinous misdeeds in order not to ruin their reputation with the public at large. The excellent acting by the top-rate cast rates as another substantial asset: Torrent makes for a strong and sympathetic protagonist, with bang-up support from Francisco Boira as Francesca's caring and concerned husband Pedro, Hector Colome as selfless and helpful psychiatrist priest Miguel, Maria Alfonsa Rosso as tormented old amnesia victim Blanca, and Miriam Cepa as Francisca's sweet daughter Rosa. Juan Carlos Gomez's gloomy cinematography gives the picture an appropriately grayish autumnal look. Alfons Conde's spare shivery score hits the spine-tingling spot. Only the dodgy CGI effects leave something to be desired. A worthwhile fright film.
