The Fourth Wall (2019)

LIU Lu is leading a dreary and seemingly mundane life, working at a deer breeding farm. A friend, MA Hai, keeps trying in vain to win her affections. It's as if she's isolating and banishing herself from any kind of human warmth or love. MA Hai confesses he knows another LIU Lu and another himself in a 'parallel world'. The more she learns about the other 'her', the more LIU Lu uncovers about the long suppressed memories from her past.
