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.

本片由以《天下第一拳》扬威国际市场的导演郑昌和自编自导。晚唐昭宗时代，藩镇割据，镇国公李明（尹一峰）恃强作恶，鱼肉百姓，「追魂琵琶」穆俊杰（凌云）联同六刺客，订下剌杀李明的计划。穆手持六个头骨骷髅拜会李明，令李明以为心腹大患已除，再密谋行刺……导演郑昌和处理古装武侠片另有一手，本片最后一场李明在甘露河渡口避雨，穆俊杰率众夹击，大雨滂沱中，刀光剑影，血溅飞沙，是武侠电影的经典场面。值得一提的是，新人李丽丽演女侠孙美贞，光芒四射，奠定新一代武侠女星地位。
