Set in the Song Dynasty, when the men of the Yang Clan are massacred in battle, their women, from elderly grandmother to little sisters, put on armor, take up swords, and lead the army to victory -- seeking vengeance. Produced by Jackie Chan, this action-packed war epic stars Cecilia Chung as Mu Guiying, the celebrated woman warrior and Yang family daughter-in-law, as well as veteran wuxia actress Cheng Pei Pei as the 100-year-old Yang matriarch.
