A young man is obsessed with courtesan O-ume, but she refuses to meet him anymore, finding him too persistent. During a fight, the young man seemingly kills his rival, and is himself blinded. He hides in the flat which he shares with his sister, not knowing that the rival's death was only staged. A man approaches the sister, pretending to be a policeman who can help her to clear her brother from the charges with money. Also, a doctor whom the sister consults declares that her brother's eyes can be cured, but only if she can pay him. To collect the money, she offers herself as a prostitute to a procuress. When the alleged policeman attempts to rape the sister, she stabs him. Meanwhile, the brother has regained his eyesight on his own, goes to O-umes house and dies under her window, foaming from the mouth and ridiculed by O-ume and his rival. The last scene shows the sister standing at a crossway, calling in vain for her brother.
