A seaside school. In the corridor stands the principal, beloved of the high-spirited youngsters. Gazing at a picture of a whale drawn as a child, the head teacher is swept away with sentiment into a flashback from the past. Just then, on the ocean horizon...This is a story of men, whales, and their relationship over time. It illustrates how dependency on each other has reversed over the years. It is a story of past memories and future hopes told through the eyes of one Japanese man.
