Ring 2

After the body of Sadako Yamamura is retrieved from a well, her uncle Takaishi is summoned by police to identify her. Detective Omuta explains to Takaishi that forensics concluded Sadako may have survived in the well for thirty years. Forensics experts reconstruct her body, giving it to Takaishi, who gives his niece a burial at sea, hoping to be free from the guilt he has carried since her mother Shizuko committed suicide because of his actions. The police search for Reiko Asakawa following the sudden death of her ex-husband Ryuji Takayama and her father Koichi a week later. Mai Takano, Ryujiâs university assistant, investigates his death, visiting Reikoâs news office where her colleague Okazaki joins Mai in her search for answers. They find a burnt out videotape in Reikoâs apartment, Mai sensing Reikoâs father died the same way as Ryuji.
Investigating the urban legend of the cursed videotape, Okazaki meets a high school student Kanae Sawaguchi, who gives him a copy of the tape but admits she watched it herself. She begs Okazaki to watch the tape before the week is up, but he chickens out and hides his copy in his desk drawer at work.
Mai and Okazaki go to a mental hospital to speak to Masami Kurahashi, friend of Reikoâs niece Tomoko, but learn she is both mute and has a phobia of televisions, having witnessed Tomokoâs death. They meet Doctor Oisho Kawajiri, Masamiâs doctor and a paranormal researcher, who is trying to expel the psychic energy within Masami through experimentation. Mai steps out for some air, encountering Masami, whose presence causes Sadako to materialise on a television and terrify the patients.
Mai finds Reikoâs son Yoichi alone in a shopping mall before his mother appears. Mai learns Yoichi has been mute since his father and grandfatherâs deaths and his psychic abilities intensified, and Reiko asks if Kawajiri can help. Returning to the hospital, Mai, Okazaki, and Detective Omuta observe Kawajiriâs experiment to exorcise the psychic energy from Masami by projecting her mental imagery onto a blank tape. However, it causes the cursed videotapeâs imagery to appear, killing Masami, and Mai destroys the recording. Upon learning Kanae has died from the curse, Mai surrenders Reiko and Yoichi to the authorities. Realising the two are to be separated, Mai telepathically warns Yoichi, who escapes with Reiko, who is consequentially hit by a truck. Okazaki attempts to delete his interview with Kanae, only for her ghost to materialise and haunt him.
Mai and Yoichi travel to Oshima Island and stay in the Yamamura inn. Yoichi has a nightmare, causing Shizuko's and a young Sadakoâs ghosts to appear before Mai wards them away. Dr. Kawajiri arrives in the night, offering to exorcise Yoichi as he tried with Masami, with Mai volunteering to act as a conduit to expel Sadakoâs hatred into a swimming pool, water being able to neutralise the energy. However, the attempt turns frightening, Sadakoâs coffin appearing in the pool. Takaishi drowns himself to stop Sadako, while Kawajiri goes insane and commits suicide by diving into the pool carrying electrical equipment.
Mai and Yoichi fall into the water, appearing inside the well. Ryujiâs ghost appears, absorbing Sadakoâs rage from his son, and summons a rope that will guide Mai to safety as long as she doesnât look down. Mai ends doing so, causing Sadakoâs ghost to appear, who scales the well only to cryptically ask, âWhy is it only you were saved?â, before falling back into the well. Mai and Yoichi emerge in the pool, free of their fear. While Okazaki is institutionalised, a nurse discovers he is haunted by Kanaeâs laughing spirit.
