Serpent Temple.

After the fall of the Ming Dynasty, Yushin's descendants organized an underground party called Cheonjidang to found a new Ming Dynasty and collected and hid tens of thousands of gold to be used as military funds in the future. And this hiding place was tattooed on the bodies of the young man and woman (Haewol and Gahwa). As time goes by, the right-winger plots a plan to kill all the Cheonji Party members, and while assassinating them one by one, he hears the secret story of the tattoo from a dying Cheonji Party member. On the other hand, Sunamgeom's assistant inspector captures Woopaja and hangs him on the execution ground along with Gahwa and then tells Haewol about this. Haewol appears at the execution site and fights to the death before saving her father and his fiancée.
