From Wikipedia: The Grudge 2 is a 2006 supernatural horror film and a sequel to the 2004 film The Grudge. Produced by Sam Raimi, the film was directed by Takashi Shimizu, written by Stephen Susco and stars an ensemble cast that includes Amber Tamblyn, Arielle Kebbel, Jennifer Beals, Edison Chen, Sarah Roemer and Sarah Michelle Gellar. As stated by Shimizu, the film is not a remake of any Japanese film and follows a different storyline. Like its predecessor, the film features a plot that is told through a non-linear sequence of events and includes several intersecting subplots. The three main subplots include: Karen's younger sister Aubrey coming to Japan after finding out about Doug's death, a schoolgirl named Allison being hunted by the ghosts after entering the house with two of her classmates and a young boy named Jake whose apartment building is haunted by the ghosts of the Saeki family.
