Kaidan

is a 2007 Japanese horror film directed by Hideo Nakata. It centers on two young lovers who are haunted by the ghost of a murdered moneylender who seeks revenge, which leaves a lasting effect on the couple. Plot In feudal Japan, Oshiga (Kuroki) and Osono are sisters whose father has been killed by Shinzaemon, a samurai, due to a debt dispute. Upon his death, Oshiga and Osono's father vowed revenge for his wrongful murder. His body is dumped in a mysterious lake that's believed to be cursed and haunted by a woman who was wrongfully killed by her husband many years ago. Shortly after, Shinzaemon kills his wife and himself, leaving their baby, Shinkichi, orphaned and in care of his uncle. Years later, Oshiga, now a respected teacher who runs a school for young girls in Edo, falls in love with a young tobacco vendor named Shinkichi (Kunoemon Oroe), who lives with his uncle. Shinkichi and Oshiga decide to live together as husband and wife, but Shinkichi begins flirting with the school's students, especially Oisa. Miserable and invidious, Oshiga becomes mean to the students, who leave one by one. Oshiga also quarrels with Osono, who doesn't approve of her relationship with Shinkichi, prompting Osono to run away. Shinkichi admonishes Oshiga for driving away her sister and declares he wants to end their relationship. Oshiga pleads with him not to leave. During this quarrel, Shinkichi accidentally wounds his wife with her shamisen's bachi against her left brow. They reconcile, but Oshiga slowly falls ill from her wound. Later, at a festival, Oisa meets Shinkichi, who is there to buy medicine for Oshiga, and they rent a hotel room. There he promises to run away with her. Shinkichi then goes to his uncle's house to find that Oshiga is waiting for him. Oshiga states that he can leave but asks him to promise to stay by her side when she dies.
