Punch

Poor and rebellious but timid 18-year-old Wan-deuki has a father afflicted with kyphosis, commonly known as being hunchback. His live-in uncle isn't completely normal, either. His Filipino mother, missing for much of his life, appears out of the blue. But when his radical and combative schoolteacher, Dong-joo-who is every bit the troublemaker Wan-deuki is-corrals the fight-prone youngster into channeling his rage as a kickboxer, Wan-deuki learns what family truly means.
Based on the novel by Kim Yeo-ryung and adapted screenplay by Kim Dong-soo, PUNCH was one of Korea's biggest box office draws in 2011. It begins firmly rooted in the coming-of-age genre, but turns into a family and social drama that addresses issues such as education, disability, multiculturalism and the generation gap.
