Flash Future Kung Fu (1983)

Original title: 打擂台

The battle for survival rages in a computer-run world.

Imagine an old-school martial arts melodrama about competing fighting schools dropped into the grungy sci-fi world of Blade Runner, and you have an idea of the curious mix of styles in Flash Future Kung Fu. Eddy Ko is the maverick star pupil of an honorable school who secretly engages in underground "Black Boxing" bouts, a black market sport off limits to the school. The ambitious X-Gang, a bloodthirsty neo-Nazi-like organization, plots to take care of Ko and his friends and take over the city with their army of mind-controlled zombie soldiers. In true Hong Kong fashion, it boils down to a showdown of champions, and this one takes place in a boxing ring in an eerily empty warehouse with video coverage broadcasting the event all over.
