Death Duel (1977)

The Third Master (Erh Tung Sheng, aka Derek Yee, in the role that launched his career) is considered to be the greatest sword master of the day. His displays of skill and strength bring armies of challengers to his door, seeking the title for themselves. Not to be defeated, the Third Master fights evil, saves damsels in distress, and duels rival swordsmen to the death.
