Under the rule of King Heng, the masses have no means to live. People of lofty ideals form an alliance and take a "Belt Oath" to overthrow King Heng and bring peace to the people. King of Heng asks a martial arts master Marquis Wei to find the "Belt Oath" and kill everyone on that list. Both Bai Shanshui and Xie Rou are on the list. Xie Rou's brother Xie Changsheng is attracted by the beauty of Bai Shanshui. He pretends to be an official Xuan Wu and goes to the inn to pursue Bai Shanshui. And Bai Shanshui mistakes Xie Changsheng as Xuan Wu who she wants to see. Two martial arts masters and Xie Rou also come to the inn. It's quite messy and the hidden crisis gets more dangerous, which causes a series of ridiculous and serious events.
