An American martial artist serving in the military, who decides to leave the army to compete in a martial arts tournament in Hong Kong where fights to the death can occur.
''Bloodsport III'' reintroduces the character Alex Cardo (Daniel Bernhardt) from ''Bloodsport II''. As Alex travels to India and gambles in a casino, masked men steal money and a package from the casino, but not before Alex beats up several of the men. After the robbery, the casino owner convinces Alex to retrieve the package (a bag of diamonds) from the robbers, since they belong to a mob boss named Duvalier (John Rhys-Davies). Alex does so, and Duvalier invites him to a dinner party he's hosting as thanks.
