Spy Nation is Newstapa's first feature-length documentary film and the directorial debut of veteran journalist Choi Seung-ho. The film, which caused a stir when it was released, follows the case of Yoo Woo-sung, a North Korean defector and former Seoul city official, whose sister falsely confessed that her brother was a spy based on the fabricated evidence. The filmmakers use their investigative journalism skills to track down the truth beyond the facts. They don't just dictate the National Intelligence Service's announcement that Mr. Yoo confessed, but question and trace the process and reasons for his confession. As a result, the truth we see is shocking. In the history of espionage operations dating back to the early days of the Korean War, confessions have been the most reliable and easiest evidence for public security agencies, and there are well over 100 victims who were ultimately exonerated. The presence of Choi Seung-ho, who relentlessly follows and interviews the presidential secretary and the head of the National Intelligence Service, who are responsible for the case, is also an important sanction of the film. It is no exaggeration to say that Spy Nation is an achievement of a Korean journalistic documentary that shines with the will to reveal the truth and the courage to protest against injustice.
