Bruce Lee has done the impossible ... He's surpassed himself!

Bruce plays Chin Chin, a martial arts student in Shanghai, whose sifu is killed by a rival Japanese martial arts school. He decides to take it upon himself to exact retribution by soundly thrashing the whole of the Japanese school's students. When they retaliate the police step in. Chin Chin goes under cover to ferret out the guilty parties and kills the two spies who murdered his sifu. Now he is on the run with both the police and the Japanese after him. He carries on until all the guilty ones are dead, and then gives himself up. He dies by running and leaping at the cops waiting to take him in. Bruce's take on the end was that Chin Chin had to die since he committed murder, and could not go unpunished.

There are some excellent classic fight sequences in the film, notably the one pitching Bruce against the whole Japanese school and the final fights against the hired Russian the Japanese throw at him - played by Bob Wall - and the main villain. Jackie Chan was the stuntman Bruce kicked through the window, though you can't see his face. Also stars Nora Miao. In the US the film is known as The Chinese Connection.
