The special takes place in the sea paradise, Okinawa. Hosho Reiko’s butler, Kageyama, leaves for Hong Kong to give Reiko’s father, Seitaro, a yearly report. Though there had not been too many major incidents as of late, while Kageyama is away, a major incident occurs, where a burnt corpse of a man who is thought to be Matsushita Keizan, a world renowned artist, is discovered.

After the usual round of questioning suspects, Reiko returns home to find that Kageyama is finally back from his week long trip. When Reiko tells Kageyama about the case involving the discovery of Matsushita Keizan’s burnt body, Kageyama takes Reiko to the Hosho family’s art storage and while showing her Matsushita’s collection, he informs Reiko that he suspects that it is a locked room mystery situation. Reiko makes fun of Kageyama for having the same opinion as Kazamatsuri. Kageyama, with his damaged pride for being at the same level as Kazamatsuri, swearing that he will figure out the mystery, asks Reiko for more details of the crime. They contemplate for a while whether it really was a murder or if it was a suicide, and eventually settle on the idea that it was indeed a suicide. As they decide to return to dinner, Reiko suddenly remembers another major incident that had occurred. This incident had in fact occurred on a trip to Okinawa that Detective Kazamatsuri had arranged.
