The story revolves around Keiko Nakadai, who in the beginning is an Office Lady working at the perpetually last-place ATV television network. However, she is chosen to fill in for weather reporter Michiko Kawai for one night, and Keiko takes full advantage of her opportunity by blatantly flashing her panties while on live television. The incident causes the evening news ratings to jump, and because of ATV's desperation to escape the ratings cellar, Keiko is subsequently promoted to full-time weather reporter, displacing Michiko in the process. The rest of the series focuses on her rivalries with co-workers jealous of and insulted by the nature of her success.
