The theatrical release date is 10/11/1973 from Golden Harvest with Angela Mao, James Tien, Pai Ying, Lam Kau, Lee Kwan, Lily Chen Ching, Cliff Lok, Jason Pai Piao and action director Chen Kuan-Tai. 1973 was Angela Mao's third year with Golden Harvest and this movie came out just after "Enter the Dragon" and "When Taekwondo Strikes". It opens with Angela training and the men watching in admiration. Problem is, I did not see much to admire in the initial performance and that was the standard for the entire movie. The return of Pai Ying (as Hung Wei) is announced. He arrives and they have the usual introductory challenge fights. Next Chen Kuan-Tai and his bandit gang barge in but Pai Ying quickly sends them to Hell. There is a plot line involving a treasure map broken up into four and tattooed on four brothers backs. The brothers must leave the fort to defend attacks on their other schools. James Tien encounters Jason Pai-Piao. The fights are standard stuff and heavy on the trampoline jumps despite Chen Kuan-Tai listed as action director. Angela discovers the truth and they fight and she is prisoner. James also finds the truth, fights, and he flees. Angela and James then join forces and train for the standard final fight against Pai Ying. Though Chan Kuan-Tai and Angelao Mao are real martial artists and this was the year when it had to be real, thank you Bruce Lee, my only complaint was that all the fights looked alike, lacked style and creativity. I can't rate it any higher than above average and that was due to the execution of the moves only.
