During the turbulent days at the beginning of the Chinese revolution, a secretive rebel leader, Wan (Ku Feng), arrives in town looking to recruit people to the cause. One of the first things he witnesses is the playfully arrogant swagger of local man Meng (Chiang) as he beats a couple of soldiers in a brief exchange of fisticuffs. Wan approaches Meng and asks for his help in a particularly testing mission: the audacious theft of a large consignment of rifles and ammunition that can then be transported to the rebels in the south. Meng is immediately keen on aiding this cause and happily agrees to the mission with no interest in financial gain. He also suggests employing his hot-headed, but no less politically impassioned brother Tieh (Lung) and young firebrand Pepper (Ching Li) whose father has access to a large fleet of trucks. After persuading the aforementioned allies to join the cause, Meng and his employer devise a plan to get the rifles out of the army barracks where they reside. The idea is eventually successful and the rifles are loaded onto trucks to be moved south to the intended rebel enclave. However, local General Chin begins to realise that someone has tricked him out of the rifle horde and sends his troops out to find those responsible, recovering the load in the process.
