With help from the treacherous
Song dynasty general Pun Mei, the
Khitan-ruled
Liao dynasty army succeeds in trapping the loyal Song general Yeung Yip and his seven sons at Golden Beach. Yeung Yip and his sons are all killed or captured in the ambush, except for the 5th son and the 6th son, who manage to escape. The 6th son returns home, but is severely traumatised by the events, resulting in tantrums. Meanwhile, the 5th son seeks refuge in a
monastery in
Mount Wutai, but the monastery leaders initially do not consider him calm enough to be a
Buddhist monk. As blades are not allowed inside a monastery, he uses his training in
spears to practise with a
pole, eventually developing the unique
eight diagram pole fighting technique. When he finally appears to have put his anger and past behind him, news breaks that the Khitans have captured his younger sister, Yeung Baat-mui, who has been looking for him. Now he must break his Buddhist vows, which include not killing any living being and not being bothered by worldly affairs, to save Baat-mui and exact his revenge. ==Cast==
