In the Warring States Period of ancient China (475-221 BCE), Xin and Piao are war-orphans in the kingdom of Qin. They dream of one day proving themselves on the battlefield. One day, however, Piao is taken to the palace by a minister. Winding up on the losing side of a power-struggle, Piao manages to return to the village, barely alive. Xin then meets a boy who closely resembles Piao, Ying Zheng. For now he is the king of Qin; later he will become the emperor Qin Shi Huang.
