The Fugitive.

Siu Lao (Lieh) and Ma Tien Piao (Feng) are bandits who ride from town to town holding up banks and killing anyone who tries to stop them using their superb and rapid fire shooting skills. When a holdup goes wrong, Siu sends Ma away with the cash and tells him that if he is caught to try and rescue him later. Siu is tortured and as time passes he realizes his sworn brother isn't coming for him instead setting up a bandit gang to carry on with murdering and banditry. Sui manages to escape and heads for Ma's encampment to settle some scores.
