The Angry Guest (1972)

Duel Of Fist was another hit from the "iron triangle" of director Chang Cheh and stars David Chiang and Ti Lung. And, as with all the director's classics, one good hit deserves another, so this sequel was called for. When last we left our heroes, they had triumphed against evil in Thailand. But a vengeful Japanese gangster has their mother killed and one of their girlfriends kidnapped.
