Fei, a fisherman who is secretly a highly skilled
swordsman, saves Yan Shisan, the 13th prince of the
Yan kingdom, and befriends him. While Yan Shisan is recovering from his injuries, the fishing village comes under attack by assassins sent by Yan Shisi, Yan Shisan's 14th brother who has usurped the throne. Fei leads Yan Shisan to hide in a remote tomb, where the prince expresses his wish to work with his ally, the Lord of
Lanling, to seize back the throne. Fei then goes to find the Lord of Lanling's daughter Yueya'er. While escorting Yueya'er back to the tomb to meet Yan Shisan, they are attacked by an assassin and Fei is wounded. While Fei is recuperating under Yueya'er's care, they fall in love with each other. However, Yueya'er feels torn as she has already been betrothed to Yan Shisan. The assassin who attacked Fei earlier turns out to be Moxian'er, a guardian originally sent by Yan Shisi to find an opportunity to kill Yan Shisan. Moxian'er has been delaying her mission because she has gradually fallen in love with the prince over time. After Yueya'er meets Yan Shisan at the tomb, the prince decides to hold their wedding in the autumn and offers to make Fei a general. Fei, who is used to a carefree lifestyle, turns down the offer. One night, after Yan Shisan's men are mysteriously killed, Moxian'er accuses Yueya'er of having a secret affair with Fei, and tries to kill Yueya'er. However, Yueya'er also accuses Moxian'er of being a spy working for Yan Shisi. Eventually, Yan Shisi leads his soldiers to the village and kills the villagers. Yan Shisan is forced to face Yan Shisi in a fight, during which Moxian'er sacrifices herself to save Yan Shisan. Fei, despite being seriously wounded, manages to defeat and kill Yan Shisi. Yueya'er also dies of her injuries in Fei's arms. == Cast ==
