In this historical martial arts epic, Detective Dee (Mark Chao, Young Detective Dee, Monga) is appointed by Emperor Gaozong to protect the Tang Dynasty from rival Empress Wu (Carina Lau, 2046, Days of Being Wild) and is bestowed with the magical Dragon Taming Mace. Wu orders Yuchi Zhenjin (Feng Shaofeng, Wolf Totem, White Vengeance) of the Golden Gard to recruit five mystics and task them with stealing the threatening Mace, the consequence of which is capital punishment for Dee.
Storming the Department of Investigation, Wu orders a demonstration of sorcery power which goes horrifically wrong with deadly consequences. In the confusion, Yuchi Zhenjin is seen killing colleagues of the Golden Gard. It falls to Detective Dee to solve the puzzle and redress the balance of power to save the Tang Dynasty.
Legendary director Tsui Hark (The Taking of Tiger Mountain, Once Upon a Time in China, The Banquet) returns to direct the third film in the immensely successful series, which has racked up over USD$200m at the box office and bagged 20+ major award nominations with a star-studded cast that is just as award-worthy.
