This film begins with the prototype of a sportscar developed by the Tiger Motor Corporation failing to make a high-speed turn and subsequently crashing into a fiery wreck. To further add to the company's misfortune, their main rival, the Yamato Motor Corporation, has sent spies to the test site and they have recorded everything. Not long afterward, information is received that Yamato Motors is also developing a new sportscar and it has the same identical features of the one being built by the Tiger Corporation. Needless to say, this shocks the senior members of Tiger Motors who quickly come to the conclusion that there is a well-placed spy within the top levels of their company and, in response, a senior executive by the name of "Toru Onoda" (Hideo Takamatsu) is tasked with uncovering his identity. Not only that, but in order to stay competitive with their main rival, Onoda turns to one of his lieutenants named "Yutaka Asahina" (Jiro Tamiya) to use whatever means are necessary to cultivate their own sources of information within Yamato Motors as well. Yet, even though Asahina is extremely loyal to the Tiger Motor Corporation, what he doesn't realize is the extent to which Onoda is prepared to go to achieve his corporate agenda. Now, rather than reveal any more, I will just say that this film turned out to be surprisingly good in that it showcased a man's struggle to somehow maintain his loyalty to the company while at the same time remaining true to his conscience. This becomes especially evident with the manner in which he pressures his fiancé, "Matsuko Usami" (Junko Kano) to do things against her better judgement. Be that as it may, although it's clearly dated and doesn't contain as much suspense as I would have liked, it's still an entertaining film and I recommend it for viewers looking for a good corporate espionage movie.
