Friends Charles and Chi visit Mainland China and discover an ancient cave that houses what is supposed to be the makeshift tomb of the legendary martial artist Lung Gim-Fei. The friends find an old spell book and practice some magic, which unintentionally breaks open a wall and releases a dormant princess and her handmaiden. Charles and Chi take the Princess and her Handmaiden back to Hong Kong with them, unaware that they were followed by the just-awakened evil warlord, Tien Chien.
