Bizarre incidents have occurred one after another in the Japanese scientific community. Officials of the Pharmaceutical Society were killed by poison gas. Misfortunes also occurred one after another from the Electrical Society, engineering professors at S University, and technical officials from the Ministry of Railways. Technician Fukushima was suspected of being involved in these incidents. He became a spy under the instructions of the Minister of War, trying to find clues to the international killing group. At a scientific conference, poison gas suddenly attacked, resulting in the death of many society presidents, and the Mukushima technician was accidentally arrested. Since then, the killings of scientists have been suspended, but Dr. Onimura's conspiracy has gradually emerged. He is actually the leader of an international murderous group and plans to release poison gas to massacre citizens. Can the Mukushima technicians successfully stop the conspiracy? What will be the fate of the International Killing Corps?
