A dozen years have passed since the second Contest of Mount Hua. A new generation of martial artists are vying for recognition in the jianghu, but as the fall of their country looms closer, the making of a hero depends on more than mere kung fu skills.

Placed under the care of the Quanzhen Sect at their base in the Zhongnan Mountains, Penance stumbles across the mysterious history behind the founding of this most respected martial school and embarks on a journey during that forces him to come to terms with his family's past as well as secrets of his own heart.
