The four most dreaded words that confront a film reviewer are "based upon true events." The phrase is always a euphemism; in the case of "Bloodsport" (citywide)--a rocking, socking martial-arts saga--one can only suspect it means that if the film makers touched upon anything remotely true, it was quite unintentional.
The story centers on an event called the Kumite, a no-holds barred contest held every five years in Hong Kong. Our hero, Frank Dux (Jean Claude Van Damme), is a French-born American schooled in the martial arts by a former Japanese champion. He heads to the Far East to win and to do honor to his teacher, who is awaiting the outcome from his deathbed.
