One Armed Boxer

Tien Lung is the best fighter at the Ching Te martial arts school. The Hook Gang are part of a local opium-dealing and prostitution ring run by a man named Chao. Tien and his friends easily defeat the Hook Gang both in a restaurant and again in the valley where they have a battle royale. Chao hires a group of mercenary martial artists from Shanghai to destroy the school and all of their businesses.
