This controversially explicit Japanese film is based on a true story set in pre-war Japan. A man and one of his servants begin a torrid affair, and their desire becomes a sexual obsession so strong that to intensify their ardor, they forsake all, even life itself. Original title was Ai no Corrida.
This includes a scene of women sitting and juggling small stones during a singing game. It's on screen for a good while and is very interesting to watch.
