Butterfly & Sword
During the Ming Dynasty, there was a power struggle between Eunuch Tsao and Eunuch Lee. Tsao teamed up with Lady Kao, the head of "Happy Wood", to intercept a confidential letter sent by Lee to Sun Yu-Po, the owner of Hill Villa, in order to reveal Lee's conspiracy. Ko's pal, Mon, snuck into the villa and was placed in an important position by Sun who even arranged to have his concubine marry him. On the night of the Mid-Autumn Festival, Lady Kao and her two pals attacked the villa and succeeded in acquiring the letter. However, they discovered that the disturbance was provoked by Tsao.
