Ryoichi has cut all ties with contemporary society and now leads a hermit's existence atop a snow-covered mountain, where he is self-sufficient and lives in isolation while sending postal bombs to the heads of various corporations and television networks. In the course of one of his forays through the woods, he comes upon a beast of unknown origin. In the middle of the night, his older brother, who had recently passed away by suicide, shows up at his cabin. After passing through a door, Ryoichi is taken by the ghost to a place where he is told the truth about his family.
