Kurobara Junko (Hamabe Minami) is a struggling idol with a pure and innocent image. However, she is actually a rather devious young lady who is orchestrating the downfall of a rival. Her manager Abe Genzo (Rokkaku Seiji) gets her a job to be the chief of a police precinct for a day to raise public awareness of road safety and crime prevention. Junko accepts the role at a small police precinct but she somehow gets entangled in a murder case. In the middle of a parade, a serial killer going by the name Judge of Justice murders an influential person. The event gets cancelled and Junko is unhappy. Detective Todo Shusaku (Higashide Masahiro) from the Tokyo Metropolitan Police Department’s First Investigative Division always shows up when there is a murder case in the precinct’s jurisdiction. Junko tricks him with her favourite tactic and he is forced to investigate the case with her. Although Todo treats her like a doormat, Junko keeps prying. This odd pair end up cracking the case in one day.
