In 2004, American social worker Karen Davis tried to burn down the Saeki house to stop the curse, but failed, finding herself hospitalised and haunted by Kayako. Karen's younger sister, Aubrey, goes to Tokyo to retrieve her. In Japan, Aubrey struggles to communicate with the hospital staff but a journalist named Eason aids her. Aubrey briefly speaks with Karen, who panics and has to be restrained. Karen is later killed by Kayako in front of Aubrey and Eason. Eason explains the curse to Aubrey, revealing he rescued Karen from the house fire and has been investigating the Saeki murders and surrounding events.
