The world’s greatest detective, Ippei Kuroda, is back and this time hired by a politician to find his estranged daughter. When the daughter is found dead, the mystery deepens. Meanwhile, Kuroda’s assistant tries to stop her arranged marriage to a country hick by shacking-up with a composer who writes symphonies on his calculator — when he’s not groping women on the Tokyo trains!
Ayame, a courtesan, attracts the attention of street vendor Kisuke and decides to run away with him to America. Unfortunately, a crazed tattoo artist is obsessed with Ayame's perfect skin as a potential canvas, so he kills Kisuke to keep Ayame in Japan. Later, Ayame is sold to a brothel in Yokohama. Kisuke's ghost possesses her, causing his image to appear tattoo-like on her skin whenever she has sex.
