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,[3] written by Stephen Susco[4] 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.[5] 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.
