Snake in the Eagle's Shadow

It's toward the end of the Ching Dynasty in China and a 200 year old feud known as the deadly Eagle Claw society have eliminated all styles except for the Snake Fist style of martial arts. An evil Eagle Claw master known as Lord Sheng Kuan (Hwang Jang-lee) is obsessed with eliminating any member of the Snake Fist schools, so him and his clan go out to hunt down the last practitioner of the Snake Fist, Grandmaster Pai Cheng-cheh ("Simon" Yuen Siu-tien). Pai Cheng-cheh goes into hiding disguised as a beggar looking for his last surviving student not knowing that he was killed by Lord Sheng Kuan, he also doesn't know that the city he's hiding in is infested with Lord Sheng Kuan's men. One day, an abused poor orphan named Chien Fu (Jackie Chan) "who can't fight and has no friends except for his cat" finds Pai Cheng-cheh being bullied around by rivals of the Eagle Claw school, he goes to help him. After that incident, Pai Cheng-cheh decides to teach him the Snake Fist style so he can defend himself when trouble arrives but will that be enough to stop Lord Sheng Kuan and his men?
