Output: The story is set in Jin, a ducal state under the Zhou dynasty, during the Spring and Autumn period in ancient China. Zhao Dun, the chancellor of Jin, and his son, General Zhao Shuo, have a feud with General Tuan Gu. Tuan Gu secretly murders the Duke of Jin and pushes the blame to the Zhao family, using that as an excuse to massacre the Zhao family. The sole survivor is Zhao Shuos baby son, Zhao Wu, whose mother is the Dukes elder sister, Lady Zhuang. Lady Zhuang pleads with Tuan Gus subordinate, Han Jue, to spare her child. She then instructs Cheng Ying, a physician, to bring the child to Gongsun Chujiu, a friend of the Zhao family, before committing suicide. When Tuan Gu learns that the orphan had escaped, he slashes his sword at Han Jues face in anger and disfigures him. Tuan Gu then issues an order to seal the gates and to gather all newborn babies in the city. The plan was to identify the Zhao orphan since Tuan Gu was counting on the person hiding the baby to not hand over the baby to him, hence singling out the one baby left in the city to be the Zhao infant. Cheng Ying brings the baby Zhao Wu home, but his wife gives the child to the searching soldiers. Cheng Ying then asks Gongsun Chujiu to bring his wife and his real son disguised as Zhao Wu out of the city, while he stays behind to try and retrieve Zhao Wu from Tuan Gu. Tuan Gu finds Cheng Ying suspicious, but Cheng lies that the Zhao orphan has been taken out of the city by Gongsun Chujiu. Tuan Gu then leads his soldiers to Gongsun Chujius house and finds Cheng Yings wife and son. Mistaking Cheng Yings son for the Zhao orphan, Tuan Gu kills the infant, Gongsun Chujiu and Chengs wife. Cheng Ying is devastated by the loss of his family and he swears vengeance on Tuan Gu. He pretends to pledge allegiance to Tuan Gu and brings Zhao Wu along with him and raises the child in Tuans house. Tuan Gu mistakenly believes that Zhao Wu is Cheng Yings son and adopts Zhao Wu as his godson. Zhao Wu gradually grows up under Tuan Gus tutelage and develops a close bond with Tuan. Cheng Ying also forges a close friendship with the disfigured Han Jue and they secretly plot to help Zhao Wu avenge his family. One day, Cheng Ying breaks the truth to Zhao Wu, telling him that Tuan Gu, who has been a fatherly figure to him for the past 15 years, is actually the murderer of his family. Zhao Wu is unable to accept the truth initially but his attitude changes as he hears from Han Jue about how Cheng Ying sacrificed his own son to save him. Zhao Wu and Cheng Ying finally confront Tuan Gu, but Tuan is aware of Zhaos true identity, because, over the years, he has noticed that the boy resembles Zhao Shuo. Zhao Wu engages Tuan Gu in a sword fight but is no match for the latter. At the critical moment, Cheng Ying sacrifices himself to give Zhao Wu an opportunity to stab and kill Tuan Gu. The film ends with a dying Cheng Ying having a vision of his reunion with his family.
