The sex training of pretty Female investigator Nanami NanaMovie

As there is a wave of female kidnappings in Tokyo, Nanami Nana from the Secret investigator bureau gets assigned to the case. She has to face an evil organization that kidnaps ladies and confines them, in order to sexually train them and convert them to slaves. The case is complicated as the criminal organization has several hideouts. So Nana has to resort to asking the help of a convicted criminal, who is an evil mastermind with a very high IQ (silence of the lambs much? Yes.). An evil doctor who was also in the police force as a Criminal Psychologist. The dude has also a thing for females and for raping, so he toys around and plays mind games with Agent Nana.
