Wei Xiaobao (Stephen Chow) was escorting Princess Jianning (played by Qiu Shuzhen) to marry in Yunnan, and encountered the assassination of the one-armed nun on the way. After Xiaobao was captured, he used the excuse of worshipping the nun as his teacher, but in fact he wanted to pursue her apprentice A Ke (played by Li Jiaxin).
