Chaos

As "Chaos" begins, businessman Takayuki Komiyama is enjoying lunch with his wife. He soon returns to his office. Immediately, he receives a phone call informing him that she has been kidnapped. With his apartment full of cops, he gets another call asking him to meet the kidnapper. However, the kidnapper eventually extorts money from his victim's sister. Then the screen fades to black, and we see these events from Mrs. Komiyama's point of view. It turns out that she knows the kidnapper, Goro Kuroda, and that they have arranged a fake abduction in order to test Takayuki's faithfulness. She seems to enjoy the situation, especially when Goro ties her up.
