A samurai kills a Blind Man who tells him to “repay his debts.” Because of the samurai’s actions his entire family is to bear a terrible curse.
From Aurum Encylopedia of Horror, p.197 (CONTAINS SPOILERS!):
This harrowingly gruesome and macabre story derived from Rensaburo Shibata’s tale, recounts a family curse in all senses of the term. The plot proceeds in three phases: a poor samurai (Matsuhiro Tomura) kills a blind moneylender (Nobuo Kaneko) and sets the curse in motion as the victim’s ghost drives the killer insane, causing him to murder his wife and them commit suicide. The blind man’s daughter, also the lover of one of Tomura’s sons (Masakazu Tamura) is accidentally killed, and, crazed with grief, the boy takes to a life of crime. The third movement is inaugurated by the samurai’s second son (Yunusuke Kawazu). While courting a music teacher, played by Saeda Kawaguchi, he is seduced by the evil Hiroku Sakurai, who poisons her rival. As always in the Kaidan genre, this disfigures the victim, who is subsequently killed by her suitor before he flees with his femme fatale.
At the point, the story starts working up to its climax: the fleeing brother finds the severed head of his criminal sibling and is then haunted by the ghost of the woman he killed, which drives him to murder his lover. In addition, his mother reveals that his dead lover was also his half-sister. The family curse ends when he murders the old woman (his father’s lover) before committing suicide. Shibata’s original story combined motifs from various well-known ghost stories (including KYOREN NO ONNA SHISHO, 1962), but Hase’s frenetic direction gives this family romance of murder, mutilation, passion and incest a power all its own.
