I am thankful the days of murky nth generation VHS tapes are gone, and you can find fan dubs (and subs) of wonderful movies that were enjoyable yet barely watchable due to the quality of said tapes. This happens to be one of them, the first in a series of several movies starring the same costumes if not all the same actors. I'd never even heard of it until the mid-90s and then got to see this plus several of the sequels, most of which I don't remember much at all.
Anyway, our heroes aren't really heroes, more like thieves with honor who don't like to kill and are adored by the lower class. Think Robin Hood, men in masks.
