With shades of Talk To Her, a hopeless balding dude has a one-sided relationship with a woman in the building where he is concierge – every night he drugs her and sleeps with her, the only witness a young girl across the hall, who is blackmailing him. He is Luis Tosar (Miami Vice, The Limits of Control), very friendly and polite to the residents, but depressed and secretly causing all sorts of misery for them. Things are looking bad for César: police investigate the threatening letters Clara is getting, he’s caught inside her apartment and fired, he kills Clara’s boyfriend, but César gets the last word, a year later confessing to Clara in a letter that he’s the father of her baby. A good, tense variation on the recent home-invasion horrors from the perspective of the invader.
