After the separation of the two Koreas, communications were completely interrupted. Just as most South Koreans had no idea what was going on in the North, most North Koreans had no idea what was going on in the rest of the world.
During the Korean war, Americans were already shelling the North with propaganda leaflets. Decades later, the civilian population in South Korea began organising campaigns to launch balloons transporting leaflets denouncing the politics of the North. North Korea replied by launching balloons in the South - and so the propaganda warfare began. As the two countries were completely unable to communicate with each other, this propaganda warfare became the only way of communication between the two Koreas. With the advancement of technology, those actions gradually modernised from leaflets to USB thumb drives containing movies, from documentaries transported by balloons or rice filled plastic bottles thrown over the border towards the North Korean shore to Drones transporting memory cards the size of a thumb across the Chinese border. A lot of North Korean defectors admitted being inspired to leave the country after watching some movies and tv series from the South.
Untruth is an attempt at decoding this means of communication by projecting the content of the propaganda messages on the tools used to transport them.
