He moves to Seoul, South Korea, trains relentlessly and even ingests an unusual diet that includes ginseng to maximize his potential. During his ascent to the top of the boxing ranks, Kim, who also becomes a populist hero, enters into a relationship with lovely Lee Kyeong-mi (Chae Min-seo). However, their differing personalities create some problems.
