Combative sport has transcended time, and remains popular today. Is violence an inherent part of sports, or is it an inherent part of human beings? This film explores combat sports through two father-son relationships: a 33-year-old American professional MMA fighter who is combat-training his 10-year-old son, and a 47-year-old retired player of Calcio Storico in Florence, Italy, who has groomed his son to compete in a form of soccer (dating back to the 16th century) in which head-butting, punching, elbowing and choking are allowed.
