Na-mi and Sun-woo, who have been suffering from bullying and school violence throughout their school days, attempt suicide while their classmates go on a school trip. The story makes us anticipate unbearable tragedies, but the story of Hail to Hell is somehow lively and unpredictable. After the silly yet ridiculous suicide failure, the two try to take revenge on Chae-rin, who bullied them most and now lives happily in Seoul. However, their plans go awry. Ridiculously, Chae-rin, the worst bully ever, has found religion and has turned into a genuinely good person. What should they do now? Hail to Hell is a fascinating adventure story and an ironic moral drama created by a storyteller who combines outlandish planning and imagination.
