Résumé (jaquette) : Shaw Brothers fave Chi Kuan Chun plays a militia man who wants to improve his kung fu skills.
Seeking the guidance of a crazy kung fu master he learns the eagle fist and anli lock, a highly evolved form of combat which when mastered can immobilise one's opponent when the right nerve is struck.
However, he is unaware that the old master has a devious plan, to use our hero to do his dirty work for him... Great torturous training scenes and a highly original climactic end tight scene make this a must see!
