In a postwar Japan papered over with American influences, thrill-seeking good girl Makoto is rescued from a hitchhiking gone wrong by brooding biker badboy Kiyoshi. After he satiisfies her curiosity about men on a floating log jam, the youths embark on a torrid affair, much of it involving an extortion racket where they perform sexual shakedowns on well-to-do middle-aged men picked up by Makoto. There is nothing good about this film. I turned if off after the first ten or twenty minutes.
