Qin Shi Huang (Kim Seung-ho), who unified China with an army of 500,000, takes Yong-nyeo (Kim Ji-mi), the daughter of a tribal chief, as a concubine on his way back to Hanyang; after spending a night together, she asks for a slave, and he grants her Jin Seung (Kim Jin-kyu), leading to Jin Seung eventually escaping the palace and organizing a rebellion against Qin's tyrannical rule, culminating in a victorious battle against the Qin army.
