Strange events plague the Aoyama family's residence, led by samurai Aoyama Harima. Three months earlier, Harima was asked to show a family heirloom, a red Goryeo dish, to his uncle and a senior official. The dish was found broken, and Harima's attendant, Okiku, was blamed and punished. After Okiku's death, Harima, tormented by guilt, contemplates suicide but is stopped by another attendant, Oyuki. The dish must be presented to an imperial envoy, and mysterious deaths among the servants suggest supernatural involvement. As Harima seeks the truth behind the tragic events, he must confront vengeful spirits and uncover the mystery with Okiku's restless spirit aiding him in this tale of love, intrigue, and revenge.
