A couple arrives from Europe to stay at a guesthouse in Zamami Village. The husband Chris is a Swiss photographer, and his wife Meg is Japanese-American. Their conversations are in English and neither understands Japanese. Hana Hanashiro, owner of the guesthouse, and Yuhi Hanashiro, Hana’s grandson who works there, only speak Japanese. While Meg grows closer to Hana even though they do not understand each other’s language, Chris is miserable, moody and unable to adjust to the guesthouse or island environment. His stubbornly closed heart is awakened by something he sees underwater.
