A female assassin receives a dangerous mission to kill a political leader in eighth-century China.

In 8th century China, 10-year-old general's daughter Nie Yinniang is handed over to a nun who initiates her into the martial arts, transforming her into an exceptional assassin charged with eliminating cruel and corrupt local governors. One day, having failed in a task, she is sent back by her mistress to the land of her birth, with orders to kill the man to whom she was betrothed - a cousin who now leads the largest independent military region in North China. After 13 years of exile, the young woman must confront her parents, her memories and her long-repressed feelings. A slave to the orders of her mistress, Nie Yinniang must choose: sacrifice the man she loves or break forever with the sacred way of the righteous assassins.—Ipsith

In the Eighth Century, in China, Nie Yinniang is raised by Princess-Nun Jiaxin since she was a girl to be an assassin. When she is a young woman, Jiaxin sends her to kill her cousin, the governor of Weibo Tian Ji'an, who promised to marry her when she was a girl. When she returns home, she learns from her aunt, Princess Jiacheng, that when she married Tien Xing, she adopted her husband's son Tian Ji'an and asked him to marry Lady Tian, to bring political benefit to Weibo, instead of Yinniang, and sent her to live with her sister, Nun Jiaxin. Will Nie Yinniang be capable to kill Tian Ji'an?—Claudio Carvalho, Rio de Janeiro, Brazil
