A good guy - A mischievous genius

Fujishima Hiroshi (Kyu Sakamoto), a born "genius of mischief," joins a trading company in order to meet Nakahara Michiko (Kayama Yoshiko), a girl he has admired since his student days. However, he competes with his rival Kono (Tani Kanichi) to beat Michiko, and uses all sorts of business tactics to climb the corporate ladder in this salaryman screwball comedy.
