Television news reports that a young woman has been kidnapped and her belongings sent individually to her family. Zaizen Shota, the CEO of Zaizen Corporation, recalls an eerily similar case from 18 years ago. Then, as an investigator at a private detective agency, a man called Tanioka Soichiro asked him to find his daughter, Tanioka Nanae. In that case, Nanae's kidnapper also sent photos and cuttings from her dress, underwear, and nails to Tanioka. As a result of Zaizen's tampering in the Tanioka case, a suspect was never caught. Now Zaizen’s beloved daughter Mika goes missing and he too receives pieces of her belongings. Meanwhile, Zaizen's wife and Mika's mother, the beautiful Yuko, is anxiously holding on to a secret that she cannot tell anyone. As Zaizen investigates Mika’s disappearance on his own, he begins to learn about Yuko’s past while his life spirals out of control.
