Ikuo is a trader in old paper and scrap. He has been in prison because he and his boss Tomimori broke into a woman's house while collecting old paper and raped her. After his release, Ikuo visits a prostitute who works in a so-called soapland, a place where women wash men, a cover for illegal prostitution. He believes he recognizes in the woman, Mieko, the woman he raped years earlier. She says she doesn't know him, whereupon he vents his anger on her. Ikuo kills a girl and loses touch with reality. He becomes more and more disturbed and begins to lose his sight. He prepares for one last flight.
