How would a red be created? The Emergency Decree no. 9 issued to crack down the pro-democracy movement protests to rise against the Yusin (Revitalization Reform) Dictatorship on November 22, 1975. Korean Central Intelligence Agency declared, "A group of 21 Korean-in-Japan spies was arrested, who disguised as students of the Studying-in-Homeland program and penetrated into local universities." The Korean resident community in Japan was shocked and terrified at the case, and their wounds still have not completely healed, just stitched up. The production crew went to seek out the persons unjustly accused of espionage in Tokyo and Osaka in Japan. And traveling back and forth between Japan and Korea, in order to ask about the social climate in two countries at that time and how they had been created as espionage agents, they could encounter the shocking truth about the fabrication of “Koreans-in-Japan spy cases".
