Shoplifting security guard (commonly known as shoplifting G-Men) Nikaido Yuki interacts with people's hearts through work and solves the cases they encounter. Yuki has been assigned to work alone for a month to guard the Noto Shokusai Market in Nanao, Noto. Set in the scenic Noto town of Nanao & Wajima, she is involved in the murder of the same female security guard as herself. Yuki's husband, Toru and daughter, Chiaki, who are always answering machines, also visit Noto, so this is also a highlight. (Source: TBS)
