In the spring of 1992, Kim Dong Won, the film's director, met two long-term political prisoners who were charged with being communist spies from North Korea. During their 30 years in jail, the prisoners never gave up their allegiance to communism and North Korea. When they were finally released from prison, they began living in Kim's neighbourhood, and he became quite close with one of the prisoners, Cho Chang Son. Kim's film documents the former prisoners' return to mainstream Korean society and their campaign for repatriation.
