Documentary on one of the most famous branches of Japanese filmmaking, the erotic Pink film genre, known as Pinku Eiga, and the closely related Roman Porno cult films series produced by notorious Nikkatsu studios from 1971 to 1988.

Documentary filmmaker Kenjiro Fujii takes a look at the history of a distinctly Japanese brand of softcore pornography in this extensive examination of the "pinku eiga" genre (ピンク映画 Pinku eiga or Pinkeiga). For more than 40 years, so-called "pink" films have served as both a key source of revenue for the Japanese film industry as well as a launching pad for the careers of such mainstream filmmakers as Kiyoshi Kurosawa. After providing a detailed history of the still-profitable and popular genre through interviews with a variety of behind-the-scenes players and clips from such classic pink films as Fish Bait Boobies, director Fujii shifts his focus to the production of an upcoming pink film to offer a glimpse into the creative and stylistic evolution of the genre.
