Twenty year old Izumisawa Tsukiko (Nakamura Mami) is undergoing psychiatric hypnotherapy in the hopes of overcoming complete amnesia of everything prior to what has been described to her as a horrible “accident”. Her nightly dreams are filled with visions of her covered in blood and the fleeting image of a headless corpse. Her shrink, Dr. Hosono (Doguchi Yoriko) and the persistent detective Harada (Taguchi Tomorowo) both know that the the trauma causing Tsukiko’s amnesia was hardly an accident. Rather, she was witness to a horrible murder committed by her then boyfriend Tanabe (Mizuhashi Kenji) of a classmate named Kawakami Tomie, a recent transfer student into Tsukiko and Tanabe’s High school class. Since the murder of Tomie, Tanabe has disappeared, Tsukiko has lost all recollection, and Harada has been increasingly puzzled by the evidence he is gathering.
It seems that Kawakami Tomie, the same Tomie, has been murdered before. A case only a few years old involving her death remains open since, like the current case, no corpse was ever found. In fact, Harada has found many such murders of a victim named Kawakami Tomie, dating all the way back to the Meiji Era (which, for those of you counting lasted from 1868 to 1912). After examining the evidence thoroughly, Harada is rather convinced that he is dealing with something not quite human, while Dr. Hosono seems to require a little more convincing.
In the meantime, Tomie is back in full force, after being nursed by the crazed Tanabe from a mere head in a plastic bag to a full grown, demonic woman, and seems hell-bent on further destroying the life of Tsukiko. This, of course, involves Tomie’s gradual murder of all Tsukiko’s friends and the seduction of her latest boyfriend, Saiga Yuichi (Kusano Kouta). Only when Tsukiko’s recollection returns does she fully realize the monster which is Tomie.
