One Missed Call: Final (2006)
Emiri, a timid high school girl, is bullied mercilessly by her classmates, but when her friend, Asuka, stands up for her, Asuka becomes the target of the bullying instead. Emiri, not wanting to be bullied again, avoids Asuka. Worn down, Asuka attempts to commit suicide, but is saved by the school janitor and remains in a comatose state in the hospital. When the students embark on a class field trip to Korea, Asuka's other self, a vengeful consciousness calling herself "Pam", plots revenge by sending disturbing photos of grisly deaths to the students cell phones. Accompanying these photos is the message: 'Death exemption by forwarding the message.' With one horrific death occurring after another, Emiri races to find the key to the mystery while her classmates rush to pass the message on to save their own lives, sparking a deadly fight for survival.
