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. Connor discovers that the woman was kept by Eddie Sakamura, the son of a man Connor knew in Japan. And while Web thinks that they should bring Eddie in, Eddie asks Connor for some time to prove his innocence. Connor gives it to him, cause he is beholden to Eddie's father. But when evidence shows that Eddie's the killer, Connor and Smith are in hot water with their superiors, and when they try to get Eddie, a high speed chase ensues with Eddie getting killed. But Connor still thinks that there is something funny going on, especially when he discovers that the evidence they were given is false.
