Thousands of years ago in ancient China, only a swordsman (Tommi Eronen), the son of a blacksmith, could kill the demon (Taishen Cheng) who was harming the world. He could gain eternal life after killing the demon. Before dueling with the demon, the swordsman fell in love with a beautiful woman (Zhang Jingchu). The swordsman fought against his fate for love and gave up the chance to kill the demon, hoping to be reborn and reunite with the person he loved. Thousands of years later in modern Finland, the swordsman finally realized his wish. However, when he learned about his mission thousands of years ago, what should he do? The first Sino-Finnish co-production epic love film "Jade Warrior" is adapted from the Finnish national epic "Kalevala", which is full of mythology and lyricism. The film was shot in Finland, Estonia and Hengdian Film and Television Base in Zhejiang, China. The epic and magnificent ancient Chinese scenes combined with the cold modern Finland make the mysterious beauty of Finland's exotic and leisurely texture of the ancient Chinese city fully play out. The film’s action scenes set the pace for the emotional story, and the thousand-year love story is staged magnificently.
