The Grudge is described as a curse that is born when someone dies in the grip of extreme rage or sorrow. The curse is an
entity created when the person dies. Those who encounter this supernatural force die, and the curse is reborn repeatedly, passing from victim to victim in an endless, growing chain of horror. The following events are explained in their actual order; however, the film is presented in a nonlinear narrative. In 2004, American social worker
Karen Davis tried to burn down the Saeki house to stop the curse but failed, finding herself hospitalized 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 later falls to her death courtesy of Kayako in front of Aubrey and Eason. Eason explains the curse to Aubrey, revealing that he rescued Karen from the house fire and has been investigating the Saeki murders and surrounding events. The two go to the house to retrieve Kayako's diary. Aubrey intends to wait outside, but
Toshio drags her inside to curse her. Eason takes the diary to an associate, who explains that Kayako's mother, Nakagawa Kawamata, was an
itako who exorcised evil spirits from visitors and fed them to her daughter. Eason and Aubrey make plans to visit Kawamata. As Eason develops photographs he took of the Saeki house, Kayako emerges from a photo and murders him. After discovering his body, Aubrey travels alone to Kawamata's remote rural home. Kawamata skeptically warns her that the curse is irreversible, before being killed by her daughter. Aubrey ventures back to the Saeki house, following an image of Karen inside. She encounters
Takeo's ghost, who reenacts the night he discovers his wife's disloyalty and snaps Aubrey's neck. In 2006, school girls Allison Fleming, Vanessa Cassidy, and Miyuki Nazawa break into the house on a dare. Allison is locked in the closet and encounters a ghost resembling Kayako (revealed to be Aubrey at the end of the film), but the girls escape. After Miyuki and Vanessa are consumed by the curse, Allison speaks with school counsellor Ms. Dale about the curse, but Dale denies its existence, revealing that she went to the house and is actually a ghost herself. Allison is haunted by the ghosts of her friends, and she eventually flees back to Chicago, where she stays with her parents. The Kimbles move into an apartment block in Chicago. A young boy named Jake is disturbed by a strange presence in the building, brought about by a hooded stranger who covers windows with newspapers. Jake's father Bill and stepmother Trish are influenced by the curse: Bill, possessed by Takeo's spirit, suspects his wife of having an affair, and she bludgeons him with a frying pan. Jake and his sister, Lacey, return from school, but Jake finds that his family is all dead. He runs into the hooded person, revealed to be Allison, who explains that the curse followed her. Kayako appears inside Allison's hood, finally taking her, and then emerges to assault Jake. ==Cast==
