Following the events of Duel of Fists (1971), the imprisoned gangster breaks out and immediately begins taking revenge against the two brothers, but his Yakuza boss in Tokyo has other plans in mind for the brothers.
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.
