This postmodern mystery-thriller from director Hiroshi Nishitani embodies a big-screen cinematization of the popular Japanese television series Galileo. Shinichi Tsutsumi stars as Ishigami Tetsuya, a brilliant but eccentric mathematician-cum-high school science teacher who develops a crush on the fetching Hanaoka Yasuko (Yasuko Matsuyuki), a saleswoman of bentos (or small, wooden lunchboxes unique to Japan). Hanaoka, as it turns out, is something of a criminal. Having successfully murdered a man in tandem with her daughter, she needs a foolproof alibi, and Ishigami draws on his scientific genius to help them construct one. The police are just as determined and resourceful, however, and enlist the support of their own scientist in the murder investigation, the equally brilliant and eccentric physicist Yukawa Manabu - who just happens to be an old classmate of Ishigami's. Thus marks the beginning of an aggressive, unchecked battle of wills between the two scientists to completely outwit one another.
