Trauma came when On’s parents passed away and left her alone. She is too afraid to go outside. Then On hears from her grandmother about the sound of the shell. The film, which expresses On’s fear and anxiety in various sound directions, creates a variety of dense sound textures. While she concentrates on the sound of the shell, the audience will listen to the screen as On’s body senses time and space as much as the resonance of the sound of the sea that the shell embraces. And such a sensation quickly takes us back to a time we might have forgotten long ago. [PARK Sohyun]
