Oume is the granddaughter of a physician, Itô Kihei. She gets smitten with Iemon and wants Oiwa out of the way. Oiwa being much prettier is an obstacle. So, Oume and Itô devise a plan and give Oiwa a face cream (which is toxic).
Oiwa applies the cream and unbeknownst to her, one of her eyes droop, and her face becomes disfigured. Iemon is aghast and repulsed by her appearance. In the meantime, Oume seduces Iemon, and this makes divorce an urgent affair. To find a valid reason, he asks his friend, Takuetsu, to rape her and later frame her for infidelity.
Genius plan, or so he thought.
Takuetsu enters the room with the purpose in mind but is horrified by what he saw. Wordlessly, he hands Oiwa a mirror. Oiwa sees her ghastly reflection and is grief-stricken. She tries covering up her disfiguration, but her hair starts falling in clumps.
Takuetsu explains Iemon’s agenda. Oiwa is hysterical and runs a sword through her throat. As she gurgles blood, she curses Iemon’s name.
