In China in the mid-1200s, Yang Guo is the orphan son of the late Han traitor Yang Kang, a sworn pact brother with the prince of Jin. Although Yang Guo is street-smart, his quest to become a martial arts master appears to be fruitless until he meets a young female expert named Xiao Long Nu. At first, he finds her cold and distant, but eventually the two form a strong bond that blossoms into a taboo romance - in this age, martial arts instructors are not permitted to form romantic relationships with their students. But as their newfound love grows, another emotion is also brewing inside Yang Guo. He has learned that Guo Jing, the man that sent him away from his home and his father's closest ally, and the plotting Huang Rong may have been behind his father's death. Yang Guo plans to take revenge but is hesitant to use his newfound fighting skills for immoral ends. Meanwhile, another threat - the invading Mongol hordes - poses another, more pressing threat to the realm, with the sound of galloping hooves growing louder from the steppes...
