Trap of suicide kilometer (1964)

Klima, Deputy Minister of Industry of the Republic of Alabanda, has come to Japan to purchase materials for the water dam construction. Kitami, who called himself a salesman and met with Klima, acts as his bodyguard. However, Kitami learns that a large number of industrial cylinders unrelated to dam construction have been purchased, and Klima secretly confined her secretary, a former army colonel, and threatened to produce poisonous gas. Klima packed the gas in a cylinder and sent it to Alabanda in an attempt to cause a civil war between the government and the tribes. Around that time, Klima secretly investigated Kitami's identity and learned that he was a secret agent.
