The three Aoi sisters live in a luxurious Japanese house. One night, Kotoko, the eldest, wakes up when she feels a presence stirring in the darkness. Her right eye gets pierced by a nail flying from the darkness. However, when the sisters check, both the nail and the eye wound have disappeared. Only leaving a bloodshed. The three sisters, who witness terrifying supernatural phenomenon, contact Jin Teshigahara, a worshiper, and his assistant Ryoan Suzuki for an exorcism. Teshigahara tells them that a curse placed on their ancestors is about to destroy the Aoi sisters. However, the exorcism ceremony was just the beginning of the Aoi sisters' 26 years of hellish revenge.
