Mamoru Hirayama, the sales manager of Clover Shoji, a women's underwear manufacturer, was selected by President Usui to be the manager of the foreign affairs section newly established in the sales department. Masaaki Sakata, Yasushi Inoda, Osamu Yamabe, and Jiro Oi were assigned to this foreign affairs section. Hirayama, a former soldier, is suddenly enthusiastic when the company orders him to join the Self-Defense Forces. One day, in the library where the records of the former army are displayed, Hirayama recalls his memories of that time. It turned out that the bundle of bills that the captain had made a mess of was packed in a box and buried somewhere.
