Teiai Group is one of Japan's largest firms. Yukio Tonegawa, a man with a larger-than-life presence and sharp intellect, works as the right-hand man of Chairman Kazutaka Hyodo. One day, the chairman commands Tonegawa to spearhead "Game of Death," an evil project that employs debtors. He rallies his direct reports and scrambles to form Team Tonegawa, only to encounter a barrage of challenges from the erratic chairman and his disloyal employees, ultimately leading to his demotion.
