A young man Ling Shih-hua (Chang Yi in a rare good guy role) is severely beaten by Japanese mobsters and left for dead on the beach. He is nursed back to health by a pretty young girl, and he vows to take revenge on the criminals. Meanwhile, Miss Tien Li-Chun (Angela Mao) comes to town with a score to settle with Ling. Apparently, her sister was jilted by Ling and she killed herself, so Tien must avenge her by taking his life. Ling begs her to spare him until after he gets his revenge, to which she reluctantly agrees, only to save his life after he gets mercilessly beaten by his enemies.
As Tien waits for Ling Shih-hua to recover so she can beat him, he runs into an old man who teaches him the art of t'ai chi. This gives him the edge he needs, and he finally destroys the leader of the gang. Angela finally jumps in to take her revenge, but Ling's girlfriend throws herself between them and begs for mercy. Tien surprisingly spares their lives and storms off into the distance, presumably to find someone else to take out her aggression on.

Tien Lung, the best fighter at the Ching Te martial arts school gets into a fight with the local Hook Gang at a restaurant where Tien Lung and his friends are dining. The Hook Gang are part of a local opium-dealing and prostitution ring run by a man named Chao and are rivals of the Ching Te school. The Ching Te school is the most prominent martial arts academy in town and controls the local clothes-dyeing and brick factories. In a quick battle, Tien and his friends easily defeat the Hook gang both in the restaurant and again later in the valley where they have a battle royale.
The beaten Hook gang members return to Chao and tell him how Tien and the Ching Te school beat them for no reason. More importantly, the Hook gang lies and tells Chao that Tien had disrespected their group. This infuriates Chao enough to go to the Ching Te dojo and challenge Tien's master, Hang Tui, to a fight. Hang Tui quickly defeats Chao, leaving him even more humiliated.
Chao plans his revenge by hiring a group of mercenary martial artists from Shanghai. This group consists of two karate experts and their teacher, a Judo master, a Taekwondo expert, two Thai boxing fighters, a Yoga expert, and two mystic Tibetan lamas (who are later revealed in the sequel to be students of an Imperial Assassin). With this group, Chao easily destroys the Ching Te school and all of their businesses, leaving everyone dead except for Tien Lung who loses his right arm. Tien Lung vows revenge and begins his training to destroy anyone and everyone who stands in his way.
