Young warrior Lee Wen (Dragon Lee) is on his way to meet his bride-to-be when he is attacked. Master Kai has made short work with local masters and is convinced of a plot against him. The resistance against the evil Master Kai is gathering a list of people who can help them take him out. Master Kai wants this list. He assembles a group of formidable top opponents to take down the opposition. Many of the resisters are killed but the leader (the father of Lee Wen's future bride) is taken prisoner. Lee Wen finds himself in the middle of this local war and is defeated, humiliated and poisoned in the leg by an arrow.
Seriously wounded, Lee Wen is rescued by a young maiden (whom he is engaged to but never have meet). His leg had to be amputated. So with the help of a wise master, his soon-to-be wife, and a steel prosthetic appendage he forges, Lee learns the 18 Kicking Styles technique and prepares to take Kai down. With new techniques and renewed confidence, the warrior sets out to find the evil Master Kai and put him and his comrades to the ultimate test and save his father-in-law. But before he can reach his enemy, Lee must stop a series of formidable opponents, including a fire-breathing man and a group of invisible women.
