Jean-Claude Van Damme makes his starring debut in the descriptively titled Bloodsport. An American soldier at large in Hong Kong, Van Damme becomes involved in the Kumite, a highly illegal kickboxing competition. Whoever survives the bout will be crowned Kumite champion of the world…a title that has plenty of challengers with homicide in their hearts. The finale offers a duel to the death between Van Damme and reigning Kumite king Bolo Yeung. The script is based on the real-life exploits of martial arts champ Frank Dux, who serves as the film's fight coordinator.

Frank Dux has spent most his life being trained by Tanaka to participate in the Kumite, the ultimate martial arts tournament, where participants are seriously injured, even killed. Frank decides to go despite being told by his superiors in the army that he can't because they need him. Two army officers are sent to get him and the trail leads to Hong Kong, but Frank eludes them. While Frank advances, he knows that he may have to face Chong Li, the defending champion, who has killed a few participants.

Billy Wong is a New York cop whose partner is murdered by Hong Kong gangsters and is assigned a new partner, Danny Gorani. They are sent to rescue an American woman who was kidnapped and taken to Hong Kong.
