To mark the 40th anniversary of the Gwangju Uprising, director and Gwangju native Lee Jo-hoon originally planned on making a documentary about the “Gwangju Video” – a compilation of foreign news footage that was secretly produced and distributed to spread the truth about the Korean military regime’s brutal crackdown on democracy protests in May 1980. However, in the course of making the film, Lee discovered that four hours were missing from archival records. He could not find any photos or footage for 1 pm to 5 pm on May 21st when soldiers opened fire on civilians in front of the Provincial Hall. What happened in those four missing hours? And why are there no records?
