In 1970, sewing worker Chun Tae-il lit a spark that changed the workers' rights movement in South Korea forever. Over two decades after his story was told in the 1995 award-winning film A Single Spark, director Hong Jun-pyo brings Chun's tragic but rousing story to animation for a new generation of audiences. While Hong's version of the story doesn't shy away from the inhumane working conditions in Seoul's Peace Market that drove Chun to become a labour activist, it also portrays Chun as more than a heroic martyr by showing him in happier times as an ordinary young man with aspirations.
