Rich heiress Reiko Hosho lives a double life as a novice detective, fighting crime under Inspector Kazamatsuri—also from a wealthy family. After work, Reiko sheds her pantsuit to don a lovely dress for dinner each day. Difficult cases force her to confide in her butler Kageyama, who proceeds to savagely ridicule her inability to solve mysteries, all while brilliantly unraveling each case himself.

Yuki Furukawa (Keita) suddenly becomes the supervisor of a Shinto shrine. The young man is thrust into the role when his father unexpectedly falls ill and is unable to organize the annual moon festival. The challenge is compounded when performers are also quitting, and others are unhappy with their roles.
