The sexy and beautiful Keiko (played by Miki Takakura) is the second wife of Yoshio Kobayashi (played by Kazuyuki Senba), the branch manager of a certain bank. The couple experiences a considerable gap in both age and personality, making their marriage dull and lifeless. One day, Keiko goes to the Shonan seaside alone to unwind, where she encounters the handsome young scavenger Nozaki (played by Hajime Inoue). The youth does not require many words, and a passionate affair ensues on this deserted beach. However, this experience brings trouble to Keiko, as she soon receives a threatening phone call, with the caller claiming to have taken photos of her infidelity and demanding a ransom of five million yen. Anxiously, Keiko heads to the destination with one million yen, only to witness an unbelievable scene in this dim, ghostly club. The club owner, Tsuchida (played by Nobutaka Masuda), is dissatisfied with the mere one million and turns to insult Keiko instead. From then on, Keiko finds herself sinking deeper into a trap of desire…
