Undergoing a nervous collapse after witnessing the drowning death of her lover, Molly (Cecilia Milocco) moved into a new apartment building upon her discharge. Convinced that she's hearing a persistent knock through her bedroom ceiling, she finds all of her neighbors--and the authorities--dismissive of her complaints. Is her torture someone's sadistic ploy, or is her psyche fissuring for good? Effective opus co-stars Albin Grenholm, Ville Virtanen. 78 min. Widescreen; Soundtrack: Swedish; Subtitles: English; bonus shorts "Mickey Bader" (2010), "Dear Kid" (2016); featurettes; theatrical trailers. In Swedish with English subtitles.
