After South- and North Korea have unified, we follow the life of a young introvert geek. Living in the slums of Pyongyang. He indulges in psychedelic party-drugs at underground raves.
He wakes up alone after losing control of himself at a party. Without his friends and lots of unread messages on his phone, he has no clue what happened. But after this incident, strange visual glitches are popping up. He thinks he might be going crazy.
Yet, his roommate, Chung-Hei, connects his experiences to old Korean shamanistic mythologies. This starts off an investigation and together they go up to Mount Paektu. All while following the thoughts of a man going insane.
Shinbyeong also contains a documentary to support the storyline. Telling you what happened to North-Korea before and after the unification. And explains real, ancient Korean mythologies to support the story.
