Ring (1998)

Two teenagers, Masami and Tomoko, talk about a videotape recorded by a boy in Izu which is fabled to bear a curse that kills the viewer seven days after watching. Tomoko reveals that a week ago, she and three of her friends watched a weird tape and received a call after watching. Tomoko goes downstairs and witnesses her TV turn on by itself. She later hears startling noises and turns around, only to be killed by an unseen force.

Days later, Asakawa Reiko, a reporter investigating the popularity of the video curse, discovers that her niece Tomoko, and her three other friends, mysteriously died at the same time, on the same night, with their faces twisted in fear. She also discovers that Masami became insane from witnessing Tomoko's death and is institutionalized in a mental hospital. After stumbling upon Tomoko's photos from the past week, Reiko finds that the four teenagers stayed in a rental cabin in Izu.

Adapted from the novel of the same name by Suzuki Koji (鈴木光司).
