In a rare reversal of typecasting, Shaw Brothers' perennial bad guy Lo Lieh breaks tradition to play the honorable and noble swordsman in The Swift Knight. It's a tale of brave knights, chivalry and fair maidens where the Swift Knight (Lo Lieh) finds himself involved in romance, court intrigue and deadly jousts while trying to protect the lives of a pair of siblings as the fate of the throne depends on them.
