Shigeru Amachi wants to marry Katsuko Wakasugi, the daughter of prominent samurai Shinjirô Asano. Asano refuses the request, belittling Amachi who promptly murders him. Shuntarô Emi witnesses the murder and promises to help him cover it up, if he in turn helps him marry Wakasugi's sister. The two tell Wakasugi that her father was murdered by a notorious criminal and they will help her get revenge. Instead, they murder her sister's fiancé and Emi runs off with her.
Months later, Amachi and Wakasugi are married and living in Edo. Amachi has fallen for Junko Ikeuchi, the daughter of a nobleman, and hatches a plan to rid himself of Wakasugi. He hires Jun Ôtomo to seduce her so that he can legally kill her, but the plan goes awry. Ôtomo ends up dead and Wakasugi is poisoned causing hideous facial deformities before she also dies. Amachi marries Ikeuchi, but the spirits of Wakasugi and Ôtomo haunt him leading him to ruin.
This is probaby the best known adaptation of the kabuki play "Yotsuya Kaidan" (there are many). It's a fairly routine film from a story and characters perspective, but the film's vibrant colours and gory, hallucinatory visuals are really something.
