Ringu 0: Birthday (2000)

"Ringu 0: Birthday" is a prequel to the original "Ringu" and takes place before 30 years before the mysterious video tape is ever found. In this movie, Sadako Yamaura is the protagonist rather than the antagonist, showing how she tried to contain her powers and her evil "alter ego"and the eventual attack by her father and becoming trapped at the bottom of the well. The film doesn't go into detail how her powers are associated with the video tape or why the person dies within seven days after viewing the video clip (unlike the American version that stated that Samara lived for seven days before dying inside the well). What we do see in "Ringu 0: Birthday" is how she tried to live a normal life as a young adult by seeing a therapist for her powers and joining a theater troupe. As soon as she joins, the other troupe members begin having bad dreams about the well and realize that it has something to do with Sadako. The director of the play realizes Sadako's connection to the ESP demonstration that her mother was involved with and plans to use her talents for his own means. Only the sound tech, Toyama, doesn't have any ill or negative feelings or ideas about Sadako. Sadako loses control of her alter ego after being exposed by a reporter whose fiancee had been killed in the original ESP demonstration. In the end, Sadako becomes one with her alter ego and her adoptive father is forced to end her rampage the only way he knows how.
