Akikazu Fujishima (Kōji Yakusho) is a former detective who lost his job, marriage and daughter after having a violent reaction to his wife's infidelity. Since then, he has become a dysfunctional, unstable alcoholic. Many years later, his ex-wife (Asuka Kurosawa) contacts him to tell him that his daughter Kanako (Nana Komatsu (actress)) has gone missing. Akikazu begins investigating the disappearance, with police detective Asai (Satoshi Tsumabuki) ostensibly helping but in truth rarely involving himself in the search. Akikazu's methods involve harassing and intimidating those he speaks to, including Kanako's former classmates and teacher (Miki Nakatani), but none of them are forthcoming. Nonetheless, he discovers that she had become involved with drug users, and suspects that they made her into an addict.
