Takako is a police detective and a single mother of a child who will soon turn 1 year old. She is described as “dirty” because she doesn’t mind taking bribes or leaking information if it is to her own advantage. The series depicts her battles with the child’s irresponsible father, her police colleagues who only think of protecting themselves, and the criminals in the cases she handles.
