Somewhere in the world there is a remote island. The sea. Lush hills. The impenetrable forest. The constantly changing weather. In a lodge by the sea, a Chinese writer immersing herself in reading and writing encounters a Japanese girl who is in a melancholic mood. Night after night some dreams lull them into sleep, but a heavy heart is lost in deep thoughts. What has actually happened and what the two girls are feeling, imagining or remembering starts to overlap.
