In 221 BC, Qin Shihuangdi conquered the rest of China. Qin's great accomplishments and also his serious faults are showed in this film. Qin adopted autocratic dictatorship and led a luxurious life: abolition of feudalism and the centralization of power in the form of a now-hereditary bureaucracy loyal to himself; burning books and burying scholars; the construction of a sumptuous palace for his concubines and also the Great Wall.
