Strange events are occurring at the residence of the Aoyama family, led by high-ranking samurai Aoyama Harima. About three months prior, Harima was requested by his uncle, Aoyama Shujin, and the senior official Doi Shukei to show them their family heirloom… a red-painted Goryeo dish, presented to them by the Shogunate. However, the dish was found broken upon arrival, causing the blame to fall on Harima’s attendant Okiku, who was then punished severely.
