At the offices of a Japanese corporation, during a party, a woman, who's evidently a professional mistress, is found dead, apparently after some rough sex. A police detective, Web Smith is called in to investigate but before getting there, he gets a call from someone who instructs him to pick up John Connor, a former police Captain and expert on Japanese affairs. When they arrive there Web thinks that everything is obvious but Connor tells him that there's a lot more going on.
