The story begins in the early Showa era of the 20th century. A mysterious old man on a train relates the disappearance of his older brother three decades ago, near the 12-story Ryouunkaku tower that once stood in the seaside town of Uozu, Japan. The mystery revolves around telescopes, peep shows, and the blurred boundary between reality and dreams.
