The Ring

Two high school students, Katie Embry and Becca Kotler, have a sleepover and discuss the urban legend of a cursed videotape that will kill anyone seven days after watching it. Katie claims she and three friends watched said videotape, but Becca does not believe her. Shortly after, supernatural phenomena occurs around Katieâs house and she is killed by an unseen force. Becca, witnessing Katieâs death, is institutionalised.
At Katieâs funeral, her aunt Rachel Keller, a journalist from Seattle, is asked by her sister Ruth to investigate Katieâs bizarre death and deformed corpse. Rachelâs son Aidan possesses an extrasensory ability, claiming Katie told him she would die a week ago. Rachel discovers Katieâs three friends all died at the same time. Printing a photo reel from Katieâs bedroom leads Rachel to the holiday resort Shelter Mountain Inn, where the four students stayed. Rachel discovers the famed videotape and watches it in a rental cabin, discovering it has surreal, gruesome imagery. As soon as the tape ends, the cabinâs telephone rings and a girlâs voice utters âSeven daysâ.
Rachel enlists help from Noah Clay, her ex-boyfriend and Aidanâs father. A video analyst, Noah is sceptical of the tapeâs curse but watches it, asking Rachel to copy it for examination. Rachel studies the video, discovering hidden imagery of a lighthouse. She identifies it as the lighthouse of Moesko Island, connecting it to a woman on the video, a horse breeder named Anna Morgan. Annaâs ranch was caught in controversy when her prize-winning horses committed mass suicide by leaping into the sea, and only ended after she too took her own life. Rachel and Noah both experience supernatural symptoms. Rachel is haunted by the ghost of a little girl, and catches Aidan watching the tape. She leaves Aidan in Ruthâs care, while she goes to Moesko Island, and Noah travels to Eola Psychiatric Hospital to gain information on Annaâs medical files.
Rachel discovers Anna had an adopted daughter, Samara Morgan, the girl who is haunting her. On the ferry to the island, a horse is spooked by Rachelâs presence, escapes its pen and falls under the ship to a bloody death. Rachel meets Annaâs widow Richard, but he dismisses her when she starts asking about Samara. She then speaks to the islandâs GP, Dr. Grasnik, who explains Samara possessed uncontrolled thoughtography, burning nightmarish images into her parentsâ minds, and was sent to the hospital. Rachel confronts Richard over Samaraâs apparent abuse, but he commits suicide via electrocution. Noah arrives, and the two search the ranchâs barn where Samara was kept, secluded from her mother. It is also implied she caused the horses to go mad. They find a burnt drawing of a tree on the wall, the same tree seen in the videotape, and on Shelter Mountain.
Travelling to Shelter Mountain, Rachel and Noah discover a water well hidden beneath the rental cabin where they suspect Samaraâs body is, assuming Richard murdered her. Rachel falls down the well, experiencing a flashback that reveals it was Anna that threw Samara down the well. Rachel then recovers Samara's corpse. Rachel does not die, the curse seemingly over. The next day, Aidan informs Rachel she shouldnât have helped Samara, revealing he is still cursed as is Noah. Noah witnesses Samaraâs ghost climb out of his television, and she (or, more precisely, her appearance) kills him.
The enraged Rachel destroys the original tape, realising she was spared because she copied it and showed it to Noah, replicating the curse. In the closing scene, Rachel helps Aidan make his own copy of the tape, and he asks what happens next, to which Rachel does not answer.
