Jessica suffers from insomnia after hearing a loud noise. The mysterious noise, as when metal collides with concrete at high speed, seems to be heard only by her. She visits a sound engineer to reproduce it, and eventually befriends an archaeologist, who studies the remains found in a tunnel under construction. Perplexed by her experience, Jessica visits a doctor who is unable diagnose her symptoms. The secrets, however, seem to be unfolding when she encounters a man who remembers everything. Master filmmaker Apichatpong Weerasethakul unravels the story of coexistents who are clearly with us, but are invisible to the eye. We also leave traces among them. The familiar places—e.g., houses, hospitals, shops, forests and pathways—can be easily overlooked. However, they co-exist with attractive truths that are hidden either intentionally or not. The screams coming out of the audio and video will remain among us for a long time after the ending credit. (PARK Sungho)
