Three North Shaolin teachers (Lu Feng, Chang Sheng, and Sun Chien) are called on by the Manchus to teach their soldiers and are urged to challenge the current South Shaolin teachers. They defeat the South Shaolin teachers and, that night, the head general (Wang Lung Wei) kills the South Shaolin teachers and blames their death on the North Shaolin teachers. The South Shaolin master sends more of his pupils, who are killed accidentally by the North Shaolin teachers. He finally sends two more (Wei Pai and Lo Meng) of his students to train with old masters and trains one student (Kuo Chui) himself with the goal of finally defeating the North Shaolin experts.
