Yuko (Hitomi Enjo), whose husband is Yonezo, the president of a construction company, drives a truck herself and runs the construction site in short pants with her butt sticking out. The employees are mellow today as well as Yuko’s sex appeal, which is both reliable and motherhood, and look at her lower body and make her crotch stand upright. However, Yonezou dies in an affair with Miyuki (Mashiro Aizawa), a high school girl. After the death of the president, the employees unite to keep the company alive, with Yuko at the center.
