Hideo Nakata follows up on the phenomenal success of Ringu -- the highest grossing Japanese film up to that point -- with this effort. In the previous film, Reiko (Nanako Matsushima) was a television reporter doing a piece on a videotape that seemed to kill those who watched it. Not long after learning that the cause of the killing was a vengeful spirit named Sadako who inhabited the video, Reiko's researcher ex-husband (Hiroyuki Sanada) died a painful death, and the fate of Reiko's son, Yoichi (Rikiya Otaka) -- who watched the tape -- was in doubt. Ring 2 opens with an autopsy of Sadako, whose supernatural rage was sparked when she was dumped in a well. Sadako's powers affect Yoichi, who survived the video and has become a medium of sorts for the wraith. Also affected is Reiko's dead husband's mistress, Mai Takano (played by pop star Miki Nakatani), whose life has become a living nightmare. Also under Sadako's power is Masami Kurahashi (Hitomi Sato), who was a schoolmate of one of Sadako's first victims. Though many try to get to the bottom of the problem -- including a psychologist (Fumiyo Kohinata) and a police detective (Kenjiro Ishimaru) -- the bodies start piling up.
