Bloodsport is a 1988 martial arts film "Based on true events in the life of Frank Dux" as portrayed by Jean-Claude Van Damme.

Plot

Based on supposedly real-life events which took place between 1975 and 1980–1981, Bloodsport tells the story of an American man named Frank W. Dux (Jean Claude Van Damme), who was trained from his youth in the ways of Ninjutsu by a Japanese master of the art, Senzo Tanaka (Roy Chiao). Primarily to honor his mentor out of gratitude and respect for having been allowed the training in place of Senzo Tanaka's deceased and only son, Dux leaves for Hong Kong to participate in the Kumite — an illegal and underground, freestyle, single-elimination and occasionally deadly full-contact martial arts tournament to which the world's best martial artists are clandestinely invited every five years.
