Reclusive hero Jin Fei, (Ti Lung) known as the King Eagle, inadvertently gets involved in the internal conflicts of the Tien Yi Tong sociaty, after he falls in love their 7th chief, Yuk Lin (Li Ching)

The glorious thing about films like King Eagle is that we can step into the world of humble beginnings and marvel at greatness in the making. It's like watching old B&W films and recognizing faces that today are the biggest names in the industry. King Eagle is your prototype, lone wandering swordsman tale that further solidifies the soon to be, penultimate Shaw Brothers' director Chang Cheh on the precipice of greatness. Ti Lung's future, lone wandering, swordsman characters can be traced to this film's influences. We can also witness a break out action role for Shaw Brothers' "baby and acting queen" of drama Li Ching.—Celestial Pictures

"King Eagle" Chan Fei, a solitary knight, meets a dying swordsman. He is Chu Hung, Tien-I Gang's 6th leader, who reveals their first leader Hung Ching-tien murdered their chief in a power struggle. Returning home, Chan is met by Hung and his cohorts. A fight ensues, but Chan is the superior swordsman. Hung then orders villains Tu and Pa to kill Chan, but with the aid of swordswoman Yen Yu-lien, Tien-I Gang's 7th leader, Chan slays his two would be assassins. Undaunted, Hung sets another villain, Wen Hao-pa, on Chan. Wen agrees to kill him provided he will then become Tien-I Gang's chief. Reluctantly, Hung promises. Entering the Tien-I hideout, Chan and Yu-lien fight a gory battle, in which Yu-lien is fatally wounded by a poisoned pin. Dying, she entreats Chan to spare her evil sister, Ping-erh. The latter is unintentionally slain, however, by Wen. Finally, Wen and Hung themselves are killed. Chan resumes his solitary course.—Celestial Pictures
