Directed by Takashi Shimizu, The Grudge follows volunteer homecare worker Rika Nishida (Megumi Okina), whose altruism leads her to Chiharu (Yui Ichikawa), a catatonic old woman slowly dying in a home filled with years worth of accumulated filth. Rika's suspicion is aroused when, during the course of her volunteer duties, she can't help but sense an overwhelming feeling of dread. Eventually, Rika opens an old wardrobe only to discover a malevolent boy who introduces himself as Toshio (Yuya Ozeki). It seems as though the house was formerly occupied by a young couple -- Katsuya (Kanji Tsuda), Chiharu's son, and his wife, Kazumi (Risa Matsuda). Sadly, Kazumi was killed thanks to Toshio shortly after moving in, and it wasn't long before Katsuya met a similar fate. When one of Rika's colleagues alerts the local authorities, an investigation turns the house inside out and exposes an ancient and deadly history.
