Alongside its trademark tokusatsu Toho also had a sideline in genre-hopping B-movie comedy of which Kichachi Okamoto’s Blueprint of Murder (暗黒街の弾痕, Ankokugai no Dankon) is a prime example. Playing into a zeitgeisty anxiety about corporate corruption which led to several series of films revolving around industrial espionage such as Yasuzo Masumura’s Giants & Toys and the later Black Test Car, Okamoto’s ironic take on noir and globalisation anticipates the spy spoofs Toho would produce in the wake of Bond fever while quietly also perhaps poking fun at Nikkatsu’s crime melodramas.
The film opens with a young man, Kusaka (Ko Mishima), and his boss Komatsu (Ichiro Nakatani) testing an experimental car engine that would be ultra efficient and cheap to produce. The test goes well, but Kusaka is run off the road on the journey home, caught between a truck and a mysterious man on a motorcycle. Meanwhile, Kusaka’s brother Jiro (Yuzo Kayama), a whale hunter, is busy working on a new kind of harpoon when he gets a telegram from an old friend telling him to come home right away because his brother is dead. On meeting with Komatsu, Jiro starts to think perhaps his brother’s death wasn’t an accident. It seems there are a lot of people interested in this technology, some of whom would rather it not see the light because cheap, efficient engines are not good news for the oil industry.
Hearing that Kusaka was recieving threatening letters, Jiro wonders why he wouldn’t go to the police, but Komatsu points out that it would have made no difference. Firstly, the police rarely get involved with cases of corporate espionage, and secondly if they did the blackmailers would win anyway because if there were a court case they would have to make full disclosure of their plans. Jiro tries going to the police himself and showing them that he has evidence, as well as the “instinct of a whale hunter”, which suggests that his brother was murdered, but nonchalant policeman Azuma (Tatsuya Mihashi) doesn’t seem very interested. Teaming up with an old uni friend, Sudo (Makoto Sato), who now runs some kind of scandal rag newspaper and is well connected around town, Jiro tries to investigate but soon becomes entangled in a complicated web of corporate intrigue.
Sudo, whose paper seems to be on the verge of bankruptcy, has some sort of game going with corrupt businessman Otori (Seizaburo Kawazu) who runs Goei Economic Reporting Agency which was one of three companies bidding for Komatsu’s engine. Later, Sudo’s main squeeze Tomiko (Kumi Mizuno) also tries to blackmail Otori by posing as the daughter of a man he drove to suicide after poaching technology from his company. Played at his own game, Otori is extremely disturbed to have this traumatic incident thrust in his face, and it quickly becomes clear that although he was onboard with various kinds of corporate duplicity, he had his lines and is worried to think someone might have crossed them on his behalf.
Otori is right to worry, they are coming for him too. Eventually unmasked, it will come as no surprise to know that the big boss is from Hong Kong making this another quiet instance of Sinophobia betraying an essential anxiety about a newly global Japan. Meanwhile, Jiro’s problems are closer to home. He starts to doubt Sudo, warned off him as man only interested in money, and witnessing him play every angle to his own advantage. Sudo may be playing his own game but has his friend’s interest at heart and is simply trying to protect him from endangering himself in a world he does not understand.
Rather than the fulfilment of a dangled romance, what we’re left with is the restoration of the friendship between the two men in which they ultimately re-inhabit their innocent student selves complete with a surreal game of air baseball while Tomiko and Komatsu’s sister Kyoko (Mie Hama) cheer excitedly from the sidelines. Okamoto throws in a killer punchline to an early whale hunting gag while piling on the absurdist humour in characteristic style with one unexpected pay off after another even as the guys find themselves in an increasingly murky world of corporate double cross, femme fatale nightclub singers with their own identical minions/backing bands, and rowdy gangsters while trying to ensure the little guy is still free to innovate outside of consumerist concerns.
