Osamu Nagahama (Gyuzo) was a private detective who specialized in finding cheating partners. One day he was doing an interview in a "love hotel" and heard the scream of a young woman from the next room. Osamu somehow rescued her but he was beaten by the man. This woman was suffering from amnesia. Since she had no place to go, Osamu named her Noriko (Minori Hatsune) and hired her as an assistant.
Now this new case was concerning the infidelity of a housewife. The target Ikuko (Sayuri Shinohara) had a kindergarten child and had an affair with a doctor, Takahashi. She even planned to arrange someone to murder her husband so she could obtain his fortune. Osamu, who was a divorced with a small daughter, was infuriated by Ikuko.
However, the client Saburo also had a young mistress (Reika Hozumi). Osamu resolved the double infidelity of this couple.
Once he thought the matter was closed, the next problem occured: Noriko was kidnapped. Who did this? And what was the purpose? Who was Noriko really...!?
