西班牙女导演Gracia Querejeta的首部长片，获巴拉多利德国际电影节特别奖。 As he does at the end of every summer, Antonio climbs onto his roof to sweep out his chimney. From this vantage point, he sees that repairs have begun on one of the neighbouring houses - the one formerly inhabited by the "Nazi" (a guy's name), which after ten years of abandonment is known to the whole neighbourhood as the "mystery house". With the arrival of fall, Antonio will uncover love, deception, and death, by watching through his window.
