The big budget martial-arts An Empress and The Warriors is set in a period where the country is at war and dukes of the different kingdoms battle for land and power. Kelly Chen (“Infernal Affairs”) plays Princess Fei- er who is commanded by her dying father on the battlefield to defend their country with General Xue-hu (played by Donnie Yen).

Despite the erroneous title "An Empress and the Warriors", or literally 江山美人 "The Yangtze River, certain Mountain and the Beauty", that suggests a story of an empire of southern locality, it is fairly reasonable to perceive this piece as a romance of the northern kingdom of Yan during the Warring States period (c. 400BC - 221BC, equivalent to the Greek city-states). This intuitive impression is supported by evidences such as the use of bronze weapons, terracotta-style armor, the First-Emperor-type warrior-king at the battle front (a popular misconception perhaps inspired by the deeds of Alexander the Great), the sheer mention of Yan and Zhao states (to the Chinese, they are like Athens, Sparta etc.)The film's storyline is set in a period where the country is at war and dukes of the different kingdoms battle for land and power. Kelly plays Princess Fei-er (飛兒公主) who is commanded by her dying father on the battlefield to defend their country with General Xue-hu (played by Donnie Yen). The princess is later attacked and injured by the treacherous official Hu Ba (played by Li Guoxing), but is rescued by a hermit Duan Lan-quan (Leon Lai). Faced with continued attack from outside and within, the princess must make some important decisions to ensure the survival of herself and her country.
