Starting as a story of a bullied young female factory worker, the film amps up its frightening tropes as it gradually escalates into a feverish nightmare. An evil boss, an abusive father, a sibling’s mysterious death, creepy dolls, ghost children, and blood-chillingly violent setpieces all come together both viscerally and metaphorically for this brooding tale of repression and the dark side of human nature.

Sunny has returned to Penang to shoot his new film about his family, without their knowledge. However he has run out of money and is struggling to shoot an essential scene. His sister, Hoon, comes by the film studio and discovers that he is shooting a warts and all film about their family. In the confrontation that follows, Sunny has an epiphany that illuminates and changes his perspective of his past.
