In the Qin Dynasty, time-traveller Hong Siu-lung has lived in seclusion with his family for twenty years.

On the brink of ultimate power after conquering the six warring states, the emperor is suddenly ambushed by a mysterious team wielding advanced weapons clearly originating from Hong’s time. Drawn together by fate again, Hong and Qin Emperor are forced to confront the long-buried conflict between them, because the future now depends on how they settle their past.
