Theatrical Release Information:
Duel of the Iron Fist

In this Shaw Brothers kung fu gangster flick, a young gang member named Chieh is exiled after a brawl ends with his mob boss father dead. When he returns after a year away, young Chieh finds that his own gang has joined forces with the one that had his father killed and now he's a target. Seeking out the other former gang members who wouldn't go along with this shift in loyalty, Chieh draws together a small but mighty army -- including his mysterious Thai half-brother -- to do battle against the rival crime syndicate that robbed him of his father and his honor. Some of the greatest knife-fighting in the history of Hong Kong action cinema is what follows. ~ Cammila Albertson, All Movie Guide
