It is based on a book about Sakurai Tomoharu (Sawamura Ikki) who fell off a ravine when trying to catch a rare "phantom butterfly". Not expecting to die so early, Tomoharu couldn’t leave his daughter Ame (Kurokawa Tomoka) by herself. Thus, he comes back home immediately as if nothing has happened except for the fact that now he’s a ghost.
