Snake in the Eagle's Shadow

An orphan who has been raised at a kung fu school, where he is treated as little more than a dogsbody and practice target for the students, has a life-changing experience after helping an old peripatetic beggar.
Everyone abuses and humiliates a downtrodden orphan until he befriends an old man, who turns out to be the last master of the snake fist fighting style. Jackie becomes the old man's student and finds himself in battle with the master of the eagle's claw style, who has vowed to destroy the snake fist clan.
